Expand description

Messages sent to the coordinator.

## Variants§

§

### Token(Result<Acquired>)

A jobserver token has become available. Sent from the jobserver helper thread.

§

### WorkItem

The backend has finished processing a work item for a codegen unit. Sent from a backend worker thread.

#### Fields

§`result: Result<WorkItemResult<B>, Option<WorkerFatalError>>`
§

### CodegenDone

The frontend has finished generating something (backend IR or a post-LTO artifact) for a codegen unit, and it should be passed to the backend. Sent from the main thread.

#### Fields

§`llvm_work_item: WorkItem<B>`
§`cost: u64`
§

### AddImportOnlyModule

Similar to `CodegenDone`, but for reusing a pre-LTO artifact Sent from the main thread.

#### Fields

§`module_data: SerializedModule<B::ModuleBuffer>`
§`work_product: WorkProduct`
§

### CodegenComplete

The frontend has finished generating everything for all codegen units. Sent from the main thread.

§

### CodegenAborted

Some normal-ish compiler error occurred, and codegen should be wound down. Sent from the main thread.
