Struct rustc_middle::middle::resolve_lifetime::ResolveLifetimes

pub struct ResolveLifetimes {
    pub defs: FxHashMap<LocalDefId, FxHashMap<ItemLocalId, Region>>,
    pub late_bound: FxHashMap<LocalDefId, FxHashSet<ItemLocalId>>,
    pub object_lifetime_defaults: FxHashMap<LocalDefId, FxHashMap<ItemLocalId, Vec<ObjectLifetimeDefault>>>,
}

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.

object_lifetime_defaults: FxHashMap<LocalDefId, FxHashMap<ItemLocalId, Vec<ObjectLifetimeDefault>>>

For each type and trait definition, maps type parameters to the trait object lifetime defaults computed from them.
