Trait Implementations

impl<'tcx> Clone for ConstVarValue<'tcx>[src]

fn clone(&self) -> ConstVarValue<'tcx>[src]

Returns a copy of the value. Read more

fn clone_from(&mut self, source: &Self)1.0.0[src]

Performs copy-assignment from source. Read more

impl<'tcx> Debug for ConstVarValue<'tcx>[src]

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

Formats the value using the given formatter. Read more

impl<'tcx> UnifyValue for ConstVarValue<'tcx>[src]

type Error = (&'tcx Const<'tcx>, &'tcx Const<'tcx>)

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

fn unify_values(value1: &Self, value2: &Self) -> Result<Self, Self::Error>[src]

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