Implements the settings mechanism from the casing policy proposal across
all three languages:
Rust:
#[spacetimedb::settings]
const CASE_CONVERSION_POLICY: CaseConversionPolicy = CaseConversionPolicy::None;
TypeScript:
export default schema({ player }, {
CASE_CONVERSION_POLICY: CaseConversionPolicy.None,
});
C#:
[SpacetimeDB.Settings]
public const CaseConversionPolicy CASE_CONVERSION_POLICY = CaseConversionPolicy.None;
Implementation details:
- Rust: proc macro validates const name against known settings, generates
__preinit__ registration, duplicate = linker error
- TypeScript: optional second arg to schema(), CaseConversionPolicy re-exported
- C#: [Settings] attribute + source generator discovers and emits registration
Also adds:
- RawModuleDefV10Builder::set_case_conversion_policy()
- CaseConversionPolicy re-exported from spacetimedb bindings crate
- CaseConversionPolicy section pushed in TS and C# module builders
