Struct rustc_infer::infer::resolve::OpportunisticVarResolver

pub struct OpportunisticVarResolver<'a, 'tcx> {
    infcx: &'a InferCtxt<'tcx>,
}

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.

Fields

infcx: &'a InferCtxt<'tcx>

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.
