Enum ScopeCompatibility 

pub enum ScopeCompatibility {
    FutureIncompatible {
        shortens_to: Scope,
    },
    FutureCompatible,
}

Marks extended temporary scopes that will be shortened by #145838 and thus need to be linted on by the macro_extended_temporary_scopes future-incompatibility warning.

Variants

FutureIncompatible

Marks a scope that was extended past a temporary destruction scope by a non-extending super let initializer.

Fields

shortens_to: Scope

FutureCompatible

Marks an extended temporary scope that was not extended by a non-extending super let initializer.

Trait Implementations

impl Clone for ScopeCompatibility

fn clone(&self) -> ScopeCompatibility

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ScopeCompatibility

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

Formats the value using the given formatter.

impl<'tcx, __D: TyDecoder<'tcx>> Decodable<__D> for ScopeCompatibility

fn decode(__decoder: &mut __D) -> Self

impl<'tcx, __E: TyEncoder<'tcx>> Encodable<__E> for ScopeCompatibility

fn encode(&self, __encoder: &mut __E)

impl<'__ctx> HashStable<StableHashingContext<'__ctx>> for ScopeCompatibility

fn hash_stable( &self, __hcx: &mut StableHashingContext<'__ctx>, __hasher: &mut StableHasher, )

impl PartialEq for ScopeCompatibility

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

Tests for self and other values to be equal, and is used by ==.

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

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.
