## Usage

The input is a hexadecimal string literal with `0x` prefix.
The size of input should be an even number.

And you can use any number of `_` in the string literal to separate it for more readable.

### Examples

```rust
use slices::u8_slice;

const VAL: &[u8] = u8_slice!("0x_1234_5678_9abc_def0");
const NULL: &[u8] = u8_slice!("0x");

fn main () {
    let val = &[0x12u8, 0x34, 0x56, 0x78, 0x9a, 0xbc, 0xde, 0xf0];
    assert_eq!(VAL, val);
    assert_eq!(NULL, &[]);
}
```
