Enum rustc_middle::ty::util::CheckRegions

pub enum CheckRegions {
    No,
    OnlyEarlyBound,
    Bound,
}

Used as an input to TyCtxt::uses_unique_generic_params.

Variants

No

OnlyEarlyBound

Only permit early bound regions. This is useful for Adts which can never have late bound regions.

Bound

Permit both late bound and early bound regions. Use this for functions, which frequently have late bound regions.

Trait Implementations

impl Clone for CheckRegions

fn clone(&self) -> CheckRegions

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for CheckRegions

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

Formats the value using the given formatter.

impl PartialEq<CheckRegions> for CheckRegions

fn eq(&self, other: &CheckRegions) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

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.
