Codec that supports the binary structure tag ++ value
where the tag
identifies the encoding/decoding of the value.
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 beforethe
valuefield. To support this, use the
framingmethod to provide a transformation to each value codec. For example,
framing(new CodecTransformation { def apply[X](c: Codec[X]) = variableSizeBytes(uint8, c) })`.
Value parameters
- by
-
codec that encodec/decodes the tag value

Codec that:
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]

Codec that supports a checksum.
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))

Provides syntax for building a DiscriminatorCodec.
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.

Codec that includes a signature of the encoded bits.
Codec that includes a signature of the encoded bits.
Encoding a value of type A

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.

Codec for n-nibble packed decimal (BCD) integers that are represented with Long

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)

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

using BitVector.indexOfSlice
but this would work only if value bits do not contain the delimiter
bits at any bit position.
