Struct rustc_infer::infer::resolve::UnresolvedTypeFinder

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

The unresolved type finder walks a type searching for type variables that don’t yet have a value. The first unresolved type is stored. It does not construct the fully resolved type (which might involve some hashing and so forth).

Fields

infcx: &'a InferCtxt<'a, 'tcx>

Implementations

impl<'a, 'tcx> UnresolvedTypeFinder<'a, 'tcx>

pub fn new(infcx: &'a InferCtxt<'a, 'tcx>) -> Self

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.
