Macro const_base::encode

macro_rules! encode {
    ($slice : expr, $config : expr $(,) *) => { ... };
}

Encodes the $slice constant into a &[u8; N] with the encoding determined by $config.

$slice slice can be a &'static str, &'static [u8; N], or &'static [u8].

Examples

Base 64

use const_base::{encode, Config};

{
    const OUT: &[u8; 4] = encode!("bar", Config::B64);
     
    assert_eq!(OUT, b"YmFy");
}
{
    const BYTES: &[u8] = b"world";

    // this macro can encode non-literal constants
    const OUT: &[u8] = encode!(BYTES, Config::B64_URL_SAFE);
     
    assert_eq!(OUT, b"d29ybGQ=");
}

Base 32

use const_base::{encode, Config};

const OUT: &[u8] = encode!(&[3, 5, 8], Config::B32);
     
assert_eq!(OUT, b"AMCQQ===");

Base 32

use const_base::{encode, Config};

const OUT: &[u8] = encode!(&[3, 5, 8], Config::B32);
     
assert_eq!(OUT, b"AMCQQ===");

Hexadecimal

use const_base::{encode, Config};

const LOWER: &[u8] = encode!(&[0xB0, 0x01], Config::HEX_LOWER);
const UPPER: &[u8] = encode!(&[0xB0, 0x01], Config::HEX);
     
assert_eq!(LOWER, b"b001");
assert_eq!(UPPER, b"B001");
