Struct EagerResolver

source 
pub struct EagerResolver<'a, D, I = I>
where
    D: SolverDelegate<Interner = I>,
    I: Interner,
{
    delegate: &'a D,
    cache: DelayedMap<I::Ty, I::Ty>,
}
Expand description

Resolves ty, region, and const vars to their inferred values or their root vars.

Fields§

§delegate: &'a D§cache: DelayedMap<I::Ty, I::Ty>

We’re able to use a cache here as the folder does not have any mutable state.
