Expand description

Maps the id of each lifetime reference to the lifetime decl that it corresponds to.

Fields

defs: FxHashMap<LocalDefId, FxHashMap<ItemLocalId, Region>>

Maps from every use of a named (not anonymous) lifetime to a Region describing how that region is bound

late_bound: FxHashMap<LocalDefId, FxHashSet<ItemLocalId>>

Set of lifetime def ids that are late-bound; a region can be late-bound if (a) it does NOT appear in a where-clause and (b) it DOES appear in the arguments.

late_bound_vars: FxHashMap<LocalDefId, FxHashMap<ItemLocalId, Vec<BoundVariableKind>>>

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

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.
