Module rustc_trait_selection::infer::outlives::env

source ·


  • The OutlivesEnvironment collects information about what outlives what in a given type-checking setting. For example, if we have a where-clause like where T: 'a in scope, then the OutlivesEnvironment would record that (in its region_bound_pairs field). Similarly, it contains methods for processing and adding implied bounds into the outlives environment.

  • “Region-bound pairs” tracks outlives relations that are known to be true, either because of explicit where-clauses like T: 'a or because of implied bounds.
