BinaryProtocolParser class

Parser for binary protocol query results.

Parses binary data returned from the native ODBC engine into structured ParsedRowBuffer instances with column metadata and row data.

toString() → String: A string representation of this object.

messageLengthFromHeader(Uint8List data) → int: Returns total v1 row-major message length (header + payload) from the first 16 bytes. data must have length >= 16. Payload size at bytes 12..15 (LE). Not valid for v2 columnar buffers.
parse(Uint8List data) → ParsedRowBuffer: Parses binary protocol data into a ParsedRowBuffer (v1 and v2; ignores a trailing OUT1 block if present).
parseWithOutputs(Uint8List data) → ParsedQueryMessage: Parses a full buffer into rows/columns and optional OUT1 outputs.

headerSize → const int: Size of the protocol header in bytes (v1 — kept for call sites that pre-date columnar and OUT1).
headerSizeColumnarV2 → const int: Size of the v2 columnar fixed header in bytes.
headerSizeV1 → const int: Size of the v1 row-major header in bytes.
magic → const int: Magic number identifying binary protocol data (ASCII "ODBC").
outputFooterMagic → const int: Trailer magic for ParamValue output slots (b"OUT1"), from the Rust engine when the call used DRT1 OUT / INOUT parameters. LE u32 of the four on-wire bytes O U T 1 (not 0x4F555431 = 1TUO).
protocolVersionColumnarV2 → const int: Columnar wire format (matches native/.../columnar_encoder.rs v2).
protocolVersionRowMajor → const int: Row-major wire format (matches native/.../encoder.rs v1).
refCursorFooterMagic → const int: Trailer for materialized ref-cursor result sets (b"RC1\0"), from RowBufferEncoder::append_ref_cursor_footer in the native encoder.
