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_thread<F, T>(_time_trace: bool, f: F) -> JoinHandle<T>where
    F: FnOnce() -> T + Send + 'static,
    T: Send + 'static,

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,
