Codec[A: Any val]¶

A bidirectional codec that decodes bytes into a value and encodes a value into bytes.

Codecs are val — immutable and shareable across actors. Small codecs compose into larger ones via combinators like Seq2, Mapped, and FlatZip.

decode takes an array and a bit offset, returning either the decoded value paired with the number of bits consumed, or a DecodeError. The array is val so byte-slice codecs like Bytes can return zero-copy views via Array.trim.

encode converts a value to bytes, returning either the encoded bytes or an EncodeError.

Public Functions¶

decode¶

[Source]

Decode a value from data starting at the given bit offset.

offset: USize val

Returns¶

((A , USize val) | DecodeError)

encode¶

[Source]

fun box encode(
  value: A)
: (Array[U8 val] val | EncodeError)

Parameters¶

value: A

Returns¶

(Array[U8 val] val | EncodeError)
