Required Methods

fn codegen_allocator<'tcx>( &self, tcx: TyCtxt<'tcx>, module_name: &str, methods: &[AllocatorMethod], ) -> Self::Module

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.

Provided Methods

fn supports_parallel(&self) -> bool

Returns true if this backend can be safely called from multiple threads.

Defaults to true.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
