Trait Implementations

source

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

source

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

Returns a copy of the value. Read more

1.0.0 · source

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

Performs copy-assignment from source. Read more

source

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

source

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

Formats the value using the given formatter. Read more

source

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

source

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

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

source

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

This method tests for !=.

source

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. Read more

source

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. Read more
