see Ty::outer_exclusive_binder for details

Implementations

impl FlagComputation

fn new() -> FlagComputation

pub fn for_kind(kind: &TyKind<'_>) -> FlagComputation

pub fn for_predicate<'tcx>(
    binder: Binder<'tcx, PredicateKind<'_>>
) -> FlagComputation

pub fn for_const(c: Const<'_>) -> TypeFlags

fn add_flags(&mut self, flags: TypeFlags)

fn add_bound_var(&mut self, binder: DebruijnIndex)

indicates that self refers to something at binding level binder

fn add_exclusive_binder(&mut self, exclusive_binder: DebruijnIndex)

indicates that self refers to something inside binding level binder – not bound by binder, but bound by the next binder internal to it

fn bound_computation<T, F>(&mut self, value: Binder<'_, T>, f: F)where
    F: FnOnce(&mut Self, T),

Adds the flags/depth from a set of types that appear within the current type, but within a region binder.

fn add_kind(&mut self, kind: &TyKind<'_>)

fn add_predicate(&mut self, binder: Binder<'_, PredicateKind<'_>>)

fn add_predicate_atom(&mut self, atom: PredicateKind<'_>)

fn add_ty(&mut self, ty: Ty<'_>)

fn add_tys(&mut self, tys: &[Ty<'_>])

fn add_region(&mut self, r: Region<'_>)

fn add_const(&mut self, c: Const<'_>)

fn add_existential_projection(&mut self, projection: &ExistentialProjection<'_>)

fn add_projection_ty(&mut self, projection_ty: AliasTy<'_>)

fn add_substs(&mut self, substs: &[GenericArg<'_>])

Trait Implementations

impl Debug for FlagComputation

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

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.
