pub struct OpportunisticVarResolver<'a, 'tcx> {
infcx: &'a InferCtxt<'a, 'tcx>,
}Expand description
The opportunistic resolver can be used at any time. It simply replaces
type/const variables that have been unified with the things they have
been unified with (similar to shallow_resolve, but deep). This is
useful for printing messages etc but also required at various
points for correctness.

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.
