Struct rustc_trait_selection::traits::query::CandidateStep

pub struct CandidateStep<'tcx> {
    pub self_ty: Canonical<TyCtxt<'tcx>, QueryResponse<'tcx, Ty<'tcx>>>,
    pub autoderefs: usize,
    pub from_unsafe_deref: bool,
    pub unsize: bool,
}

Fields

self_ty: Canonical<TyCtxt<'tcx>, QueryResponse<'tcx, Ty<'tcx>>>

autoderefs: usize

from_unsafe_deref: bool

true if the type results from a dereference of a raw pointer. when assembling candidates, we include these steps, but not when picking methods. This so that if we have foo: *const Foo and Foo has methods fn by_raw_ptr(self: *const Self) and fn by_ref(&self), then foo.by_raw_ptr() will work and foo.by_ref() won’t.

unsize: bool

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.
