Canonicalization is the key to constructing a query in the
middle of type inference. Ordinarily, it is not possible to store
types from type inference in query keys, because they contain
references to inference variables whose lifetimes are too short
and so forth. Canonicalizing a value T1 using
canonicalize_query
produces two things:Structs
Requires that
region must be equal to one of the regions in choice_regions.
We often denote this using the syntax:
