Fields

self_ty: Canonical<'tcx, QueryResponse<'tcx, Ty<'tcx>>>autoderefs: usizefrom_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.

This method turns the parameters of a DepNodeConstructor into an opaque Fingerprint to be used in DepNode. Not all DepNodeParams support being turned into a Fingerprint (they don’t need to if the corresponding DepNode is anonymous). Read more

This method tries to recover the query key from the given DepNode, something which is needed when forcing DepNodes during red-green evaluation. The query system will only call this method if fingerprint_style() is not FingerprintStyle::Opaque. It is always valid to return None here, in which case incremental compilation will treat the query as having changed instead of forcing it. Read more

Returns the argument unchanged.

Calls U::from(self).

That is, this conversion is whatever the implementation of From<T> for U chooses to do.
