Macro const_base::encode_as_str

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

Encodes the $slice constant into a &str with the encoding determined by $config.

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

Examples

Base 64

use const_base::{encode_as_str, Config};

{
    const OUT: &str = encode_as_str!("qux", Config::B64);
     
    assert_eq!(OUT, "cXV4");
}
{
    const BYTES: &[u8] = b"goodbye";

    // this macro can encode non-literal constants
    const OUT: &str = encode_as_str!(BYTES, Config::B64_URL_SAFE);
     
    assert_eq!(OUT, "Z29vZGJ5ZQ==");
}

Base 32

use const_base::{encode_as_str, Config};

const OUT: &str = encode_as_str!(&[13, 21, 34], Config::B32);
     
assert_eq!(OUT, "BUKSE===");

Hexadecimal

use const_base::{encode_as_str, Config};

const LOWER: &str = encode_as_str!(&[0xB1, 0x00, 0x0d], Config::HEX_LOWER);
const UPPER: &str = encode_as_str!(&[0xB1, 0x00, 0x0d], Config::HEX);
     
assert_eq!(LOWER, "b1000d");
assert_eq!(UPPER, "B1000D");
