scodec.codecs

Provides methods to create a "checksum codec" (encodes a bit-range to a bit-checksum and decodes bits to a bit-range).

Creates checksum implementations of SignerFactory.

Indicates a checksum over bits did not match the expected value.

Represents the ability to create a Cipher for encryption or decryption.

Used in conjunction with encrypted.

Companion for CipherFactory.

Codec that supports the binary structure tag ++ value where the tag identifies the encoding/decoding of the value.

To build an instance of this codec, call discriminated and specify the tag type via the by method. Then call one more more of the case combinators on this class.

The most general case combinators are caseO and caseP. In addition to a tag, the caseO combinator is defined by providing a mapping from A to Option[R], a mapping from R to A, and a Codec[R]. The case is used for encoding if the mapping from A to Option[R] returns a Some and it is used for decoding upon matching the tag value. The caseP combinators work the same but take a PartialFunction[A, R] instead of an A => Option[R].

If R is a subtype of A, then the mapping from R to A can be omitted. Hence, the subcaseO and subcaseP constrain R to being a subtype of A and do not take a R => A function.

Finally, the least generic case combinators are the typecase combinators which add further constraints to the subcase* combinators. Specifically, the typecase operators omit the A => Option[R] or PartialFunction[A, R] in favor of doing subtype checks. For example, the following codec is a Codec[AnyVal] that encodes a 0 if passed a Boolean and a 1 if passed an Int:

   discriminated[AnyVal].by(uint8).typecase(0, bool).typecase(1, int32)

Often, the values are size-delimited -- that is, there is a size field after the tag field and beforethevaluefield. To support this, use theframingmethod to provide a transformation to each value codec. For example,framing(new CodecTransformation { def apply[X](c: Codec[X]) = variableSizeBytes(uint8, c) })`.

Mixin for codecs/decoders that are known to discriminate by values of type D.

A trait that enables custom handling for encoding/decoding sequences.

Encodes by returning the supplied bit vector if its length is size bits, padding with zeroes if smaller than size bits, returning error if greater; decodes by taking size bits from the supplied bit vector.

Encodes by returning the supplied bit vector if its length is size bits, otherwise returning error; decodes by taking size bits from the supplied bit vector.

n-bit boolean codec, where false corresponds to bit vector of all 0s and true corresponds to all other vectors.

Codec for n-bit 2s complement bytes.

Codec that:

• encodes using the specified codec but right-pads with 0 bits to the next largest byte when the size of the encoded bit vector is not divisible by 8
• decodes using the specified codec but drops any leading bits of the remainder when the number of bytes consumed by the specified codec is not divisible by 8

This combinator allows byte alignment without manually specifying ignore bits. For example, instead of writing (bool(1) :: bool(1) :: ignore(6)).dropUnits, this combinator allows byteAligned(bool(1) :: bool(1)).

Note that aligning large structures on byte boundaries can provide significant performance improvements when converting to/from data structures that are based on bytes -- e.g., Array[Byte] or ByteBuffer.

Encodes by returning the supplied byte vector if its length is size bytes, padding with zeroes if smaller than size bytes, returning error if greater; decodes by taking size * 8 bits from the supplied bit vector and converting to a byte vector.

Encodes by returning the supplied byte vector if its length is size bytes, otherwise returning error; decodes by taking size * 8 bits from the supplied bit vector and converting to a byte vector.

Codec that encodes/decodes certificates using their default encoding.

Codec that supports a checksum.

When encoding, first the value is encoded using target, then a checksum is computed over the result the encoded value using checksum, and finally, the encoded value and the checksum are converted to a single vector using framing.encode(value -> chk).

When decoding, the input vector is split in to an encoded value, a checksum value, and a remainder using framing.decode. If validate is true, a checksum is computed over the encoded value and compared with the decoded checksum value. If the checksums match, the encoded value is decoded with target and the result is returned, with its remainder concatenated with the remainder of deframing. If the checksums do not match, a ChecksumMismatch error is raised.

For example:

    val crc32 = scodec.bits.crc(hex"04c11db7".bits, hex"ffffffff".bits, true, true, hex"ffffffff".bits)

    // Size of the string is not included in the checksum -- the `framing` codec handles adding the size *after* checksum computation
    val c = checksummed(utf8, crc32, variableSizeBytes(int32, bits) ~ bits(32))

    // Size of the string is included in the checksum
    val d = checksummed(utf8_32, crc32, peekVariableSizeBytes(int32) ~ bits(32))

Codec that encodes/decodes using the specified codecs by trying each codec in succession and using the first successful result.

Codec of Option[A] that delegates to a Codec[A] when the included parameter is true.

When encoding, if included is true and the value to encode is a Some, the specified codec is used to encode the inner value. Otherwise, an empty bit vector is returned.

Provides syntax for building a DiscriminatorCodec.

Usage:

  val codecA: Codec[A] = ...
  val codecB: Codec[B] = ...

  val codecE: Codec[Either[A,B]] =
    discriminated[Either[A,B]].by(uint8)
    .| (0) { case Left(l) => l } (Left.apply) (codecA)
    .| (1) { case Right(r) => r } (Right.apply) (codecB)

This encodes an Either[A,B] by checking the given patterns in sequence from top to bottom. For the first pattern that matches, it emits the corresponding discriminator value: 0 for Left and 1 for Right, encoded via the uint8 codec. It then emits either an encoded A, encoded using codecA, or an encoded B, using codecB.

Decoding is the mirror of this; the returned codecE will first read an Int, using the uint8 codec. If it is a 0, it then runs codecA, and injects the result into Either via Left.apply. If it is a 1, it runs codecB and injects the result into Either via Right.apply.

There are a few variations on this syntax. See DiscriminatorCodec for details.

Alternative to fallback that only falls back to left codec when the right codec fails to decode due to an unknown discriminator (i.e., KnownDiscriminatorType[_]#UnknownDiscriminator).

Either codec that supports bit vectors of form indicator ++ (left or right) where a value of false for the indicator indicates it is followed by a left value and a value of true indicates it is followed by a right value.

Codec that encrypts and decrypts using a javax.crypto.Cipher.

Encoding a value of type A is delegated to the specified codec and the resulting bit vector is encrypted with a cipher provided by the given CipherFactory.

Decoding first decrypts all of the remaining bits and then decodes the decrypted bits with the specified codec. Successful decoding always returns no remaining bits, even if the specified codec does not consume all decrypted bits.

Combinator that chooses amongst two codecs based on a given byte ordering.

Codec for an Enumeration that encodes/decodes using Enumeration.Value.id values.

Either codec that supports bit vectors of form left or right where the right codec is consulted first when decoding. If the right codec fails to decode, the left codec is used.

Codec that filters bits before/after decoding/encoding.

Note: the remainder returned from filter.decode is appended to the remainder of codec.decode.

Codec that limits the number of bits the specified codec works with.

When encoding, if encoding with the specified codec results in less than the specified size, the vector is right padded with 0 bits. If the result is larger than the specified size, an encoding error is returned.

When decoding, the specified codec is only given size bits. If the specified codec does not consume all the bits it was given, any remaining bits are discarded.

Byte equivalent of fixedSizeBits.

Codec that includes a signature of the encoded bits.

Encoding a value of type A is delegated to the specified codec and then a signature of those bits is appended using the specified SignatureFactory to perform signing.

Decoding first decodes using the specified codec and then all of the remaining bits are treated as the signature of the decoded bits. The signature is verified and if it fails to verify, an error is returned.

Note: because decoding is first delegated to the specified code, care must be taken to ensure that codec does not consume the signature bits. For example, if the target codec is an unbounded string (e.g., ascii, utf8), decoding an encoded vector will result in the string codec trying to decode the signature bits as part of the string.

Use SignatureFactory or ChecksumFactory to create a SignerFactory.

Codec that always encodes size 0 bits and always decodes size bits and then discards them, returning () instead.

Codec for n-bit 2s complement big-endian integers that are represented with Int.

When decoding, the specified codec is only given size bits. If the specified codec does not consume all the bits it was given, any remaining bits are returned with the overall remainder.

Byte equivalent of limitedSizeBits.

Codec that encodes/decodes a List[A] from a Codec[A].

When decoding, codec.decode is called repeatedly until there are no more remaining bits and the value result of each decode is returned in the list.

Codec that encodes/decodes a List[A] from a Codec[A].

When encoding, each A in the list is encoded and all of the resulting bits are concatenated using delimiter.

When decoding, the input bits are first (logically) grouped into delimiter sized chunks and partitioned around delimiter chunks. Then, the individual partitions are (concatenated and) decoded using the valueCodec and the values collected are returned in a list.

Note: This method applies specific semantics to the notion of a delimiter. An alternate (and faster) implementation could be to search for the delimiter using BitVector.indexOfSlice but this would work only if value bits do not contain the delimiter bits at any bit position.

Example:

val codec = listDelimited(BitVector(' '), ascii)
codec.decode(ascii.encode("i am delimited").require).require.value // List("i", "am", "delimited")

Codec that encodes/decodes a List[A] from a Codec[A].

When encoding, each A in the list is encoded and all of the resulting bits are combined using mux.

When decoding, deMux is called repeatedly to obtain the next bits (to decode using valueCodec) and the remaining bits (input to deMux on next iteration) until a decoding error is encountered or no more bits remain. The final return value is a list of all decoded element values.

Note: For large lists, it may be necessary to compact bits in deMux.

Codec that encodes/decodes a List[A] of N elements using a Codec[A].

When encoding, the number of elements in the list is encoded using countCodec and the values are then each encoded using valueCodec.

When decoding, the number of elements is decoded using countCodec and then that number of elements are decoded using valueCodec. Any remaining bits are returned.

Note: when the count is known statically, use listOfN(provide(count), ...).

Wraps a codec and adds logging of each encoding and decoding operation.

The logEncode and logDecode functions are called with the result of each encoding and decoding operation.

This method is intended to be used to build a domain specific logging combinator. For example:

def log[A] = logBuilder[A]((a, r) => myLogger.debug(s"..."), (b, r) => myLogger.debug(s"...")) _
...
log(myCodec)

For quick logging to standard out, consider using logFailuresToStdOut.

Lookahead version of recover -- i.e., upon successful decoding with the target codec, the original buffer is returned instead of the remaining buffer.

Codec for n-nibble packed decimal (BCD) integers that are represented with Long. This codec, despite requiring the size in nibbles, is byte-size oriented. This means it expects to parse complete bytes (even if nibble size is odd). For encoding, this codec will pad 0s on the left while, for decoding, it will fetch the size in bytes round up.

Provides a codec for an enumerated set of values, where each enumerated value is mapped to a tag.

Provides a codec for an enumerated set of values, where each enumerated value is mapped to a tag.

Codec of Option[A] that delegates to a Codec[A] when the guard codec decodes a true.

Various guard codecs and combinators are provided by this library -- e.g., bitsRemaining and recover.

Codec that limits the number of bits the specified codec works with.

If the encoded result is larger than the specified size, an encoding error is returned.

If encoding with the specified codec results in less than the specified size, the vector is right padded by repeatedly encoding with padCodec. An encoding error is returned if the padCodec result does not precisely fill the remaining space.

When decoding, the specified codec is only given size bits. If the specified codec does not consume all the bits it was given, all remaining bits are repeatedly decoded by padCodec. A decoding error is returned if any padCodec decode returns an error.

If the encoded result is larger than the specified size, an encoding error is returned.

Long equivalent of peekVariableSizeBits.

Equivalent to peekVariableSizeBits where the size units are in bytes instead of bits.

Long equivalent of peekVariableSizeBytes.

Codec that always returns an empty vector from encode and always returns (empty, value) from decode. This is often useful when combined with other codecs (e.g., the discriminated).

Creates a codec that decodes true when the target codec decodes successfully and decodes false when the target codec decodes unsuccessfully. Upon a successful decode of the target codec, the remaining bits are returned, whereas upon an unsuccessful decode, the original input buffer is returned.

When encoding, a true results in the target codec encoding a unit whereas a false results in encoding of an empty vector.

Codec for n-bit 2s complement big-endian shorts.

Codec for n-bit 2s complement little-endian shorts.

String codec that uses the supplied Charset to perform encoding/decoding.

This codec does not encode the size of the string in to the output. Hence, decoding a vector that has additional data after the encoded string will result in unexpected output. Instead, it is common to use this codec along with either fixedSizeBits or variableSizeBits. For example, a common encoding is a size field, say 2 bytes, followed by the encoded string. This can be accomplished with:

variableSizeBits(uint16, string)

The size field can be any Long codec. An optional padding can be applied to the size field. The sizePadding is added to the calculated size before encoding, and subtracted from the decoded size before decoding the value.

Codec that supports vectors of the form size ++ prefix ++ value where the size field decodes to the bit length of the value field.

For example, encoding the string (3, "hello") with variableSizePrefixedBitsLong(uint32, int32, ascii) yields a vector of 13 bytes -- the first four bytes being 0x00000028, the next 4 bytes being 0x00000003, and the last 5 bytes being the US-ASCII encoding of "hello".
