Struct rustc::ty::adjustment::OverloadedDeref [−][src]
pub struct OverloadedDeref<'tcx> { pub region: Region<'tcx>, pub mutbl: Mutability, }

this crate is being loaded from the sysroot, an unstable location; did you mean to load this crate from crates.io via Cargo.toml
instead?
An overloaded autoderef step, representing a Deref(Mut)::deref(_mut)
call, with the signature &'a T -> &'a U
or &'a mut T -> &'a mut U
.
The target type is U
in both cases, with the region and mutability
being those shared by both the receiver and the returned reference.
