Expand description

The Resolver. This is the type folding engine that detects unresolved types and so forth.

Fields§

§fcx: &'cx FnCtxt<'cx, 'tcx>§span: &'cx dyn Locatable§body: &'tcx Body<'tcx>§replaced_with_error: Option<ErrorGuaranteed>

Set to Some if any Ty or ty::Const had to be replaced with an Error.
