Module rustc_hir_analysis::collect::lifetimes

Resolution of early vs late bound lifetimes.

Name resolution for lifetimes is performed on the AST and embedded into HIR. From this information, typechecking needs to transform the lifetime parameters into bound lifetimes. Lifetimes can be early-bound or late-bound. Construction of typechecking terms needs to visit the types in HIR to identify late-bound lifetimes and assign their Debruijn indices. This file is also responsible for assigning their semantics to implicit lifetimes in trait objects.

Functions

is_late_bound_map 🔒

Detects late-bound lifetimes and inserts them into late_bound.

late_region_as_bound_region 🔒

object_lifetime_default 🔒

resolve_lifetimes 🔒

Computes the ResolveLifetimes map that contains data for an entire Item. You should not read the result of this query directly, but rather use named_region_map, is_late_bound_map, etc.
