Struct rustc_middle::ty::fold::UnknownConstSubstsVisitor

struct UnknownConstSubstsVisitor<'tcx> {
    tcx: TyCtxt<'tcx>,
    flags: TypeFlags,
}

Fields

tcx: TyCtxt<'tcx>

flags: TypeFlags

Implementations

impl<'tcx> UnknownConstSubstsVisitor<'tcx>

pub fn search<T: TypeFoldable<'tcx>>(
    visitor: &HasTypeFlagsVisitor<'tcx>,
    v: T
) -> ControlFlow<FoundFlags>

This is fairly cold and we don’t want to bloat the size of the HasTypeFlagsVisitor.

Trait Implementations

impl<'tcx> TypeVisitor<'tcx> for UnknownConstSubstsVisitor<'tcx>

type BreakTy = FoundFlags

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

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

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

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

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

fn visit_const(&mut self, c: &'tcx Const<'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.
