Enum rustc_middle::middle::resolve_lifetime::LifetimeScopeForPath

source · [−]

pub enum LifetimeScopeForPath {
    NonElided(Vec<String>),
    Elided,
}

Expand description

This is used in diagnostics to improve suggestions for missing generic arguments. It gives information on the type of lifetimes that are in scope for a particular PathSegment, so that we can e.g. suggest elided-lifetimes-in-paths of the form <’, ’> e.g.

Immutably borrows from an owned value. Read more

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
