Required Methods

fn codegen_allocator<'tcx>( &self, tcx: TyCtxt<'tcx>, module_name: &str, kind: AllocatorKind, alloc_error_handler_kind: AllocatorKind, ) -> 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.

fn target_machine_factory( &self, sess: &Session, opt_level: OptLevel, target_features: &[String], ) -> TargetMachineFactoryFn<Self>

Provided Methods

fn spawn_named_thread<F, T>( _time_trace: bool, name: String, f: F, ) -> Result<JoinHandle<T>>

where F: FnOnce() -> T + Send + 'static, T: Send + 'static,

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.
