pub struct OpportunisticRegionResolver<'a, 'tcx> {
    infcx: &'a InferCtxt<'tcx>,
}
Expand description

The opportunistic region resolver opportunistically resolves regions variables to the variable with the least variable id. It is used when normalizing projections to avoid hitting the recursion limit by creating many versions of a predicate for types that in the end have to unify.

If you want to resolve type and const variables as well, call InferCtxt::resolve_vars_if_possible first.

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.
