A THIR expression.
Fields
ty: Ty<'tcx>The type of this expression

temporary; should be None only if in a constant context

pub default fn fingerprint_style() -> FingerprintStyle
sourcepub default fn to_fingerprint(&self, tcx: Ctxt) -> Fingerprint
pub default fn to_fingerprint(&self, tcx: Ctxt) -> 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

Ctxt,
&DepNode<<Ctxt as DepContext>::DepKind>
) -> Option<T>
pub default fn recover(
Ctxt,
&DepNode<<Ctxt 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 more

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.
