//! Test that casting non-primitive types with `as` is rejected with a helpful suggestion.
//!
//! You can't use `as` to cast between non-primitive types, even if they have
//! `From`/`Into` implementations. The compiler should suggest using `From::from()`
//! or `.into()` instead, and rustfix should be able to apply the suggestion.
