For decoding/encoding base 64/32/16 strings at compile-time.
Examples
Encoding
use const_base::{encode_as_str, Config};
{
const OUTA: &str = encode_as_str!("foo", Config::B64);
const OUTB: &str = encode_as_str!(b"foo", Config::B64);
assert_eq!(OUTA, "Zm9v");
assert_eq!(OUTB, "Zm9v");
}
{
const BYTES: &[u8] = b"hello";
const OUT: &str = encode_as_str!(BYTES, Config::B64_URL_SAFE);
assert_eq!(OUT, "aGVsbG8=");
}
Decoding
use const_base::{decode, Config};
{
const OUT: &[u8] = decode!("MZXW6===", Config::B32);
assert_eq!(OUT, b"foo");
}
{
const BYTES: &[u8] = b"f000";
const OUT: &[u8] = decode!(BYTES, Config::HEX);
assert_eq!(OUT, &[0xF0, 0x00]);
}
