Struct rustc_hir_typeck::writeback::Resolver

struct Resolver<'cx, 'tcx> {
    tcx: TyCtxt<'tcx>,
    infcx: &'cx InferCtxt<'tcx>,
    span: &'cx dyn Locatable,
    body: &'tcx Body<'tcx>,
    replaced_with_error: Option<ErrorGuaranteed>,
}

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

Fields

tcx: TyCtxt<'tcx>

infcx: &'cx InferCtxt<'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.

Implementations

impl<'cx, 'tcx> Resolver<'cx, 'tcx>

fn new(
    fcx: &'cx FnCtxt<'cx, 'tcx>,
    span: &'cx dyn Locatable,
    body: &'tcx Body<'tcx>
) -> Resolver<'cx, 'tcx>

fn report_error(&self, p: impl Into<GenericArg<'tcx>>) -> ErrorGuaranteed

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.
