infrastructure/native/protocol/directed_param library

Classes

DirectedParam

A parameter with an explicit ParamDirection for the DRT1 wire path.

Constants

drt1MagicBytes → const List<int>

Little-endian DRT1 magic (Rust: odbc_engine crate bound_param module).

kDirectedParamErrorPrefix → const String

Stable error prefix, aligned with output_aware_params / native ValidationError (TYPE_MAPPING §3.1).

Functions

paramValuesFromDirected(List<DirectedParam> params) → List<ParamValue>

Converts DirectedParam rows to a legacy v0 binary ParamValue list.

serializeDirectedParams(List<DirectedParam> params) → Uint8List

Serialises DirectedParam values to a DRT1 buffer.

validateDirectedOutInOut(ParamDirection direction, ParamValue pv) → void

Client-side checks for DRT1 OUT / INOUT that the native engine will reject; fails fast with the same slugs as output_aware_params.rs.
