Module rustc_trait_selection::traits::outlives_bounds

Enums

• OutlivesBound
  Outlives bounds are relationships between generic parameters, whether they both be regions ('a: 'b) or whether types are involved (T: 'a). These relationships can be extracted from the full set of predicates we understand or also from types (in which case they are called implied bounds). They are fed to the OutlivesEnv which in turn is supplied to the region checker and other parts of the inference system.

Functions

• implied_outlives_bounds 🔒
  Implied bounds are region relationships that we deduce automatically. The idea is that (e.g.) a caller must check that a function’s argument types are well-formed immediately before calling that fn, and hence the callee can assume that its argument types are well-formed. This may imply certain relationships between generic parameters. For example:
