Trait Implementations

impl<'tcx> TypeVisitor<'tcx> for MaxEscapingBoundVarVisitor<'tcx>

fn tcx_for_anon_const_substs(&self) -> Option<TyCtxt<'tcx>>

Supplies the tcx for an unevaluated anonymous constant in case its default substs are not yet supplied.

fn visit_binder<T: TypeFoldable<'tcx>>(
    &mut self,
    t: &Binder<'tcx, T>
) -> ControlFlow<Self::BreakTy>

fn visit_ty(&mut self, t: Ty<'tcx>) -> ControlFlow<Self::BreakTy>

fn visit_region(&mut self, r: Region<'tcx>) -> ControlFlow<Self::BreakTy>

fn visit_const(&mut self, ct: &'tcx Const<'tcx>) -> ControlFlow<Self::BreakTy>

type BreakTy = !

fn visit_unevaluated_const(
    &mut self,
    uv: Unevaluated<'tcx, Option<Promoted>>
) -> ControlFlow<Self::BreakTy, ()>

fn visit_predicate(
    &mut self,
    p: Predicate<'tcx>
) -> ControlFlow<Self::BreakTy, ()>

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.
