source · pub struct CandidateStep<'tcx> {

Fields§
§self_ty: Canonical<'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.
