32 ///
33 /// Types are exposed to C bindings as structs containing opaque pointers. They
34 /// are not supposed to be inspected from C. This allows the underlying
35 /// representation to change without affecting the API users. The use of structs
36 /// instead of typedefs enables some type safety as structs are not implicitly
37 /// convertible to each other.
38 ///
39 /// Instances of these types may or may not own the underlying object (most
40 /// often only point to an IR fragment without owning it). The ownership
41 /// semantics is defined by how an instance of the type was obtained.
