Macro encode_string

macro_rules! encode_string {
    ($s:expr) => { ... };
}

Encodes s such that it can be unambiguously encoded from the beginning.

This is the same thing as encode_string, but evaluates to a constant &[u8].

Example

use sha3_utils::encode_string;

let s = encode_string!(b"hello, world!");
assert_eq!(
    s,
    &[
        1, 104,
        104, 101, 108, 108, 111, 44, 32, 119, 111, 114, 108, 100, 33,
    ],
);
