Provided Methods

fn config(&mut self, _config: &mut Config)

Called before creating the compiler instance

fn after_crate_root_parsing<'tcx>( &mut self, _compiler: &Compiler, _queries: &'tcx Queries<'tcx> ) -> Compilation

Called after parsing the crate root. Submodules are not yet parsed when this callback is called. Return value instructs the compiler whether to continue the compilation afterwards (defaults to Compilation::Continue)

fn after_expansion<'tcx>( &mut self, _compiler: &Compiler, _queries: &'tcx Queries<'tcx> ) -> Compilation

Called after expansion. Return value instructs the compiler whether to continue the compilation afterwards (defaults to Compilation::Continue)

fn after_analysis<'tcx>( &mut self, _compiler: &Compiler, _queries: &'tcx Queries<'tcx> ) -> Compilation

Called after analysis. Return value instructs the compiler whether to continue the compilation afterwards (defaults to Compilation::Continue)
