Enum rustc_middle::mir::ClosureOutlivesSubject

source · [−]

pub enum ClosureOutlivesSubject<'tcx> {
    Ty(Ty<'tcx>),
    Region(RegionVid),
}

Expand description

The subject of a ClosureOutlivesRequirement – that is, the thing that must outlive some region.

Variants

`Ty(Ty<'tcx>)`

Subject is a type, typically a type parameter, but could also be a projection. Indicates a requirement like T: 'a being passed to the caller, where the type here is T.

The type here is guaranteed not to contain any free regions at present.

`Region(RegionVid)`

Subject is a free region from the closure. Indicates a requirement like 'a: 'b being passed to the caller; the region here is 'a.

T: for<'a> HashStable<StableHashingContext<'a>> + Debug,

source

pub default fn fingerprint_style() -> FingerprintStyle

source

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

source

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

source

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
