0.1.0 #

  • Initial public release.
  • Bits: Bitwise operations on integers via Bits extension type, with Bitmask for field extraction and modification.
  • Word: Register-width variable with byte/string constructors and endian-aware serialization.
  • BitStruct / BitField: Named bit-field access within a single integer, supporting both mutable and immutable variants.
  • ByteStruct / ByteField: Keyed access to typed fields within TypedData buffers using dart:ffi native type markers.
  • WordStruct / WordField: Byte-aligned fields within a 64-bit word, with immutable copy helpers.
  • EnumMap / IndexMap: Type-safe, fixed-key maps with parallel array backing and built-in JSON serialization.
  • Serializable mixin: Declarative field schema via enum keys providing toMap(), toJson(), value equality, and immutable copies.
  • BinaryFormat / BinaryCodec: Encode/decode between typed views and raw binary integers, including fixed-point, boolean, sign, and enum formats.
  • BitsMap / BoolMap: Flag and boolean collections backed by a single integer.
  • Packet framework: Abstract packet structure with header parsing, CRC/checksum validation, payload build/parse, and PacketTransformer for stream-based framing.
  • Version model: 4-field version number backed by WordStruct with string/JSON serialization.
  • Utility extensions: NumLimits, LinearConversion, Sliceable, TypeKey, null-safe helpers, and typed data slicing.
  • TypedDataBuffer: Fixed-size BytesBuilder with persistent buffer for packet assembly.
