A context which can lower HIR’s GenericArg to rustc_middle’s ty::GenericArg.

Its only consumer is generics::lower_generic_args. Read its documentation to learn more.

Required Methods

fn args_for_def_id( &mut self, def_id: DefId, ) -> (Option<&'a GenericArgs<'tcx>>, bool)

fn provided_kind( &mut self, preceding_args: &[GenericArg<'tcx>], param: &GenericParamDef, arg: &GenericArg<'tcx>, ) -> GenericArg<'tcx>

fn inferred_kind( &mut self, preceding_args: &[GenericArg<'tcx>], param: &GenericParamDef, infer_args: bool, ) -> GenericArg<'tcx>

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
