Trait Implementations

impl<'tcx> Clone for UnifiedRegion<'tcx>

fn clone(&self) -> UnifiedRegion<'tcx>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<'tcx> Debug for UnifiedRegion<'tcx>

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

Formats the value using the given formatter.

impl<'tcx> PartialEq<UnifiedRegion<'tcx>> for UnifiedRegion<'tcx>

fn eq(&self, other: &UnifiedRegion<'tcx>) -> bool

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

fn ne(&self, other: &UnifiedRegion<'tcx>) -> bool

This method tests for !=.

impl<'tcx> UnifyValue for UnifiedRegion<'tcx>

type Error = NoError

Defines the type to return when merging of two values fails. If merging is infallible, use the special struct NoError found in this crate, which unlocks various more convenient methods on the unification table.

fn unify_values(value1: &Self, value2: &Self) -> Result<Self, NoError>

Given two values, produce a new value that combines them. If that is not possible, produce an error.

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.
