Expand description
Experimental types for the trait query interface. The methods
defined in this module are all based on canonicalization,
which makes a canonical query by replacing unbound inference
variables and regions, so that results can be reused more broadly.
The providers for the queries defined here can be found in
rustc_traits.

Structs
A set of constraints that need to be satisfied in order for
a type to be valid for destruction.
Result from the
normalize_projection_ty query.Enums
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.
