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

impl<Tcx, T> DepNodeParams<Tcx> for Twhere Tcx: DepContext, T: for<'a> HashStable<StableHashingContext<'a>> + Debug,

source§

default fn fingerprint_style() -> FingerprintStyle

source§

default fn to_fingerprint(&self, tcx: Tcx) -> Fingerprint

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).
source§

default fn to_debug_str(&self, _: Tcx) -> String

source§

default fn recover(_: Tcx, _: &DepNode) -> Option<T>

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.

source§

fn from(t: T) -> T

Returns the argument unchanged.

source§

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.
