Struct WasmBuildInputSnapshot 

pub struct WasmBuildInputSnapshot<'guard> { /* private fields */ }

Immutable prepared Cargo input resolution shared by concurrent readers.

Preparation resolves the complete declared specification set while the caller holds a genuine source write-exclusion guard. Reader batches may run concurrently through &self, but cannot introduce specifications that were not declared during preparation.

Implementations

impl<'guard> WasmBuildInputSnapshot<'guard>

pub fn prepare_assuming_sources_immutable<Guard: ?Sized>( _source_write_guard: &'guard Guard, specs: &[WasmBuildSpec], ) -> Result<Self, WasmBuildError>

Resolve and freeze the complete specification set under a source lease.

The guard must prevent mutation of every Cargo/rustc executable, manifest, configuration file, discovered source, declared additional input, and relevant environment value used by the supplied specifications. The type system cannot verify guard provenance.

pub fn build_batch( &self, specs: &[LabeledWasmBuildSpec], config: WasmBuildBatchConfig, ) -> Result<WasmBuildBatchReport, WasmBuildBatchContractError>

Build one sequential collect-all batch from prepared inputs.

Separate calls may run concurrently. Every exact specification must have been supplied to Self::prepare_assuming_sources_immutable.

pub fn build_batch_with_progress<F>( &self, specs: &[LabeledWasmBuildSpec], batch_config: WasmBuildBatchConfig, progress_config: WasmBuildProgressConfig, observer: F, ) -> Result<WasmBuildBatchReport, WasmBuildBatchContractError>

where F: FnMut(WasmBuildBatchProgressEvent),

Build one observed sequential batch from prepared inputs.

Separate calls may run concurrently and use independent observers.

pub fn metrics(&self) -> WasmBuildInputSnapshotMetrics

Current preparation, reader-reuse, and invalidation metrics.
