Implementations§

source§

impl<D, I> EvalCtxt<'_, D, I>
where D: SolverDelegate<Interner = I>, I: Interner,

source

pub fn instantiate_normalizes_to_term( &mut self, goal: Goal<I, NormalizesTo<I>>, term: <I as Interner>::Term, )

When normalizing an associated item, constrain the expected term to term.

We know term to always be a fully unconstrained inference variable, so eq should never fail here. However, in case term contains aliases, we emit nested AliasRelate goals to structurally normalize the alias.
