+//! 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`.
