// 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.
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 t1: *const [u8; 2] = &x1.y as *const _;
let h1: *const [u8; 2] = &x1.y as *const [u8; 2];
let mut x1 = X { y: [0, 0] };
// This is still an error since we don't allow casts from &mut [T; n] to *mut T.
let p1: *mut u8 = &mut x1.y as *mut _; //~ ERROR casting
let t1: *mut [u8; 2] = &mut x1.y as *mut _;
