Implementations

source

impl<'tcx> UpvarSubsts<'tcx>

source

pub fn upvar_tys(self) -> impl Iterator<Item = Ty<'tcx>> + 'tcx

Returns an iterator over the list of types of captured paths by the closure/generator. In case there was a type error in figuring out the types of the captured path, an empty iterator is returned.

source

default fn fingerprint_style() -> FingerprintStyle

source

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

source

default fn to_debug_str(&self, Ctxt) -> String

source

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
