}Expand description
Description of a type-checked function parameter.
Fields§
§pat: Option<Box<Pat<'tcx>>>The pattern that appears in the parameter list, or None for implicit parameters.
ty: Ty<'tcx>The possibly inferred type.
ty_span: Option<Span>Span of the explicitly provided type, or None if inferred for closures.
self_kind: Option<ImplicitSelfKind>Whether this param is self, and how it is bound.
hir_id: Option<HirId>HirId for lints.

default fn fingerprint_style() -> FingerprintStyle
source§default fn to_fingerprint(&self, tcx: Tcx) -> Fingerprint
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). Read more

_: Tcx,
_: &DepNode<<Tcx as DepContext>::DepKind>
) -> Option<T>
default fn recover(
_: Tcx,
_: &DepNode<<Tcx as DepContext>::DepKind>
) -> 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. Read moresource§impl<T, R> InternIteratorElement<T, R> for T

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.
