## rend in action
|
|
|
|
```rust
|
|
use rend::*;
|
|
|
|
let little_int = i32_le::new(0x12345678);
|
|
// Internal representation is little-endian
|
|
assert_eq!([0x78, 0x56, 0x34, 0x12], unsafe { ::core::mem::transmute::<_, [u8; 4]>(little_int) });
|
|
|
|
// Can also be made with `.into()`
|
|
let little_int: i32_le = 0x12345678.into();
|
|
// Still formats correctly
|
|
assert_eq!("305419896", format!("{}", little_int));
|
|
assert_eq!("0x12345678", format!("0x{:x}", little_int));
|
|
|
|
let big_int = i32_be::new(0x12345678);
|
|
// Internal representation is big-endian
|
|
assert_eq!([0x12, 0x34, 0x56, 0x78], unsafe { ::core::mem::transmute::<_, [u8; 4]>(big_int) });
|
|
|
|
// Can also be made with `.into()`
|
|
let big_int: i32_be = 0x12345678.into();
|
|
// Still formats correctly
|
|
assert_eq!("305419896", format!("{}", big_int));
|
|
assert_eq!("0x12345678", format!("0x{:x}", big_int));
