Release 1.7.0: declarative semantic-type registry (#166) + partial generated types (#167) - #168
Merged
Conversation
…nerated types (#167) Closes #166: schemas can now annotate fields with semanticType (e.g. UTCTimestampNanos, LocalMktDate, MonthYear) and the generator emits a sibling typed accessor {Field}Value alongside the raw wire field. Eight FIX/SBE built-in converters ship out of the box; users can register or override via [assembly: SbeSemanticType("Name", typeof(MyConverter))] where MyConverter implements ISbeSemanticConverter<TWire,TSemantic>. Optional fields produce nullable accessors. Field-level semanticType wins, otherwise the field inherits its referenced type's semanticType (common FIX/B3 pattern). Types already producing a typed helper struct (e.g. LocalMktDate -> DateOnly) are left untouched to avoid double conversion. Raw wire accessor is never replaced. Closes #167: SbeDispatcher, ISbeMessageHandler, {Msg}VersionMap, {Msg}DataReader, and {X}Validation are now emitted as partial so consumers can extend them in user code without forking the generator. Layout-bearing blittable structs were already partial. Adds diagnostics SBE016 (wire-type mismatch), SBE017 (does-not-implement ISbeSemanticConverter), SBE018 (semantic accessor name collision).

Release 1.7.0: declarative semantic-type registry (#166) + partial generated types (#167)
Closes #166: schemas can now annotate fields with semanticType (e.g.
UTCTimestampNanos, LocalMktDate, MonthYear) and the generator emits a
sibling typed accessor {Field}Value alongside the raw wire field. Eight
FIX/SBE built-in converters ship out of the box; users can register or
override via [assembly: SbeSemanticType("Name", typeof(MyConverter))]
where MyConverter implements ISbeSemanticConverter<TWire,TSemantic>.
Optional fields produce nullable accessors. Field-level semanticType
wins, otherwise the field inherits its referenced type's semanticType
(common FIX/B3 pattern). Types already producing a typed helper struct
(e.g. LocalMktDate -> DateOnly) are left untouched to avoid double
conversion. Raw wire accessor is never replaced.
Closes #167: SbeDispatcher, ISbeMessageHandler, {Msg}VersionMap,
{Msg}DataReader, and {X}Validation are now emitted as partial so
consumers can extend them in user code without forking the generator.
Layout-bearing blittable structs were already partial.
Adds diagnostics SBE016 (wire-type mismatch), SBE017 (does-not-implement
ISbeSemanticConverter), SBE018 (semantic accessor name collision).
