Required Methods§
fn codegen_allocator<'tcx>( &self, tcx: TyCtxt<'tcx>, module_name: &str, kind: AllocatorKind, alloc_error_handler_kind: AllocatorKind ) -> Self::Module
sourcefn compile_codegen_unit(
&self,
tcx: TyCtxt<'_>,
cgu_name: Symbol
) -> (ModuleCodegen<Self::Module>, u64)
fn compile_codegen_unit( &self, tcx: TyCtxt<'_>, cgu_name: Symbol ) -> (ModuleCodegen<Self::Module>, u64)
This generates the codegen unit and returns it along with
a u64
giving an estimate of the unit’s processing cost.
