// Issue #14893. Tests that casts from vectors don't behave strangely in the
// presence of the `_` type shorthand notation.
//
// Update: after a change to the way casts are done, we have more type information
// around and so the errors here are no longer exactly the same.
//
// Update: With PR #81479 some of the previously rejected cases are now allowed.
// New test cases added.
struct X {
y: [u8; 2],
}
fn main() {
let x1 = X { y: [0, 0] };
// No longer a type mismatch - the `_` can be fully resolved by type inference.
let p1: *const u8 = &x1.y as *const _;
let p1: *mut u8 = &x1.y as *mut _;
//~^ ERROR: casting `&[u8; 2]` as `*mut u8` is invalid
let t1: *const [u8; 2] = &x1.y as *const _;
let t1: *mut [u8; 2] = &x1.y as *mut _;
//~^ ERROR: casting `&[u8; 2]` as `*mut [u8; 2]` is invalid
let h1: *const [u8; 2] = &x1.y as *const [u8; 2];
