Required methods

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

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

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

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

pub fn join_codegen(
    &self,
    ongoing_codegen: Box<dyn Any>,
    sess: &Session
) -> Result<(CodegenResults, FxHashMap<WorkProductId, WorkProduct>), 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.

pub fn link(
    &self,
    sess: &Session,
    codegen_results: CodegenResults,
    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.

Provided methods

pub fn init(&self, _sess: &Session)

pub fn print(&self, _req: PrintRequest, _sess: &Session)

pub fn target_features(&self, _sess: &Session) -> Vec<Symbol>

pub fn print_passes(&self)

pub fn print_version(&self)

pub fn target_override(&self, _opts: &Options) -> Option<Target>

If this plugin provides additional builtin targets, provide the one enabled by the options here. Be careful: this is called before init() is called.
