Required Methods

fn kind(&self) -> &'static str

fn build<'life0, 'life1, 'life2, 'async_trait>( &'life0 self, spec: &'life1 ResolvedSourceSpec, ctx: &'life2 SourceBuildCtx, ) -> Pin<Box<dyn Future<Output = SourceResult<SourceSvcIns>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait, 'life2: 'async_trait,

Provided Methods

fn validate_spec(&self, _spec: &ResolvedSourceSpec) -> SourceResult<()>

可选：轻量级参数校验（不产生 I/O），用于尽早暴露参数错误。
