Implementations§
source§impl<'tcx> TyOrConstInferVar
impl<'tcx> TyOrConstInferVar
sourcepub fn maybe_from_generic_arg(
arg: GenericArg<'tcx>,
) -> Option<TyOrConstInferVar>
pub fn maybe_from_generic_arg( arg: GenericArg<'tcx>, ) -> Option<TyOrConstInferVar>
Tries to extract an inference variable from a type or a constant, returns None
for types other than ty::Infer(_)
(or InferTy::Fresh*
) and
for constants other than ty::ConstKind::Infer(_)
(or InferConst::Fresh
).

Layout§
Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...)
attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
