```rust ```rust
use std::mem; use std::mem;
unsafe { fn main() {
let a = [0u8, 0u8, 0u8, 0u8]; unsafe {
let a = [0u8, 1u8, 0u8, 0u8];
let b = mem::transmute::<[u8; 4], u32>(a); let b = mem::transmute::<[u8; 4], u32>(a);
println!("{}", b); // 256
// or, more concisely:
let c: u32 = mem::transmute(a);
println!("{}", c); // 256
}
} }
``` ```
