fs2.data.csv

Describes how a cell can be decoded to the given type.

CellDecoder provides convenient methods such as map, emap, or flatMap to build new decoders out of more basic one.

Actually, CellDecoder has a https://typelevel.org/cats/api/cats/MonadError.htmlcats`MonadError` instance. To get the full power of it, import cats.syntax.all._.

Describes how a cell of a given type can be encoded.

Controls the escaping when outputting CSV.

Witness that a RowF has headers of a certain type.

Raised when processing a Csv row whose width doesn't match the width of the Csv header row

A type class describing what it means to be a parseable CSV header.

Describes how a row can be decoded to the given type.

RowDecoder provides convenient methods such as map, emap, or flatMap to build new decoders out of more basic one.

Describes how a row can be decoded to the given type.

RowDecoderF provides convenient methods such as map, emap, or flatMap to build new decoders out of more basic one.

Actually, RowDecoderF has a cats `MonadError` instance. To get the full power of it, import cats.syntax.all._.

Describes how a row can be encoded from a value of the given type.

A CSV row with or without headers. The presence of headers is encoded via the first type param which is a subtype of scala.Option. By preserving this information in types, it's possible to define Row and CsvRow aliases as if they were plain case classes while keeping the code DRY.

Operations on columns can always be performed using 0-based indices and additionally using a specified header value if headers are present (and this fact statically known).

'''Note:''' the following invariant holds when using this class: values and headers have the same size if headers are present.

Low level pipes for CSV handling. All pipes only perform one step in a CSV (de)serialization pipeline, so use these if you want to customise. All standard use cases should be covered by the higher level pipes directly on the csv package which are composed of the lower level ones here.

A CSV row with headers, that can be used to access the cell values.

'''Note:''' the following invariant holds when using this class: values and headers have the same size.

Describes how a row can be decoded to the given type.

CsvRowDecoder provides convenient methods such as map, emap, or flatMap to build new decoders out of more basic one.

Describes how a row can be encoded from a value of the given type.

Higher kinded version of scala.None. Ignores the type param.

A CSV row without headers.

Describes how a row can be decoded to the given type.

Decode a char-like stream (see fs2.data.text.CharLikeChunks) into a specified type.

Scenarios:

• If skipHeaders is false, then the file contains no headers.
• If skipHeaders is true, then the headers in the file will be skipped.

For both scenarios the file is assumed to be compliant with the set of headers given.

Decode a char-like stream (see fs2.data.text.CharLikeChunks) into a specified type, assuming the file contains headers, but they shall be skipped for decoding.

Decode a char-like stream (see fs2.data.text.CharLikeChunks) into a specified type, assuming the file contains headers and they need to be taken into account for decoding.

Decode a char-like stream (see fs2.data.text.CharLikeChunks) into a specified type, assuming the file neither contains headers nor are they needed for decoding.

Encode a specified type into a CSV prepending the given headers.

Encode a specified type into a CSV that contains the headers determined by encoding the first element. Empty if input is.

Encode a specified type into a CSV that contains no headers.
