Required methods

fn metadata_loader(&self) -> Box<MetadataLoaderDyn>

fn provide(&self, _providers: &mut Providers)

fn provide_extern(&self, _providers: &mut Providers)

fn codegen_crate<'tcx>(
    &self,
    tcx: TyCtxt<'tcx>,
    metadata: EncodedMetadata,
    need_metadata_module: bool
) -> Box<dyn Any>

fn join_codegen(
    &self,
    ongoing_codegen: Box<dyn Any>,
    sess: &Session,
    dep_graph: &DepGraph
) -> Result<Box<dyn Any>, ErrorReported>

This is called on the returned Box<dyn Any> from codegen_backend

Panics

Panics when the passed Box<dyn Any> was not returned by codegen_backend.

fn link(
    &self,
    sess: &Session,
    codegen_results: Box<dyn Any>,
    outputs: &OutputFilenames
) -> Result<(), ErrorReported>

This is called on the returned Box<dyn Any> from join_codegen

Panics

Panics when the passed Box<dyn Any> was not returned by join_codegen.
