core::intrinsics::transmute

pub unsafe extern "rust-intrinsic" fn transmute<T, U>(e: T) -> U

Unsafely transforms a value of one type into a value of another type.

Both types must have the same size.

Examples

fn main() { use std::mem; let array: &[u8] = unsafe { mem::transmute("Rust") }; assert_eq!(array, [82, 117, 115, 116]); }

use std::mem;

let array: &[u8] = unsafe { mem::transmute("Rust") };
assert_eq!(array, [82, 117, 115, 116]);
