Function fast32::decoder_map

pub const fn decoder_map<const B: usize, const N: usize>(
    enc: &[u8; B],
    from: &[u8; N],
    to: &[u8; N]
) -> [u8; 256]

Build a new decoder array for the given bits (encoder array size), with additional character translations

You should use fast32::make_base32_alpha or fast32::make_base64_alpha instead of this! (Those macros invoke this function as appropriate.)

Example:

use fast32::decoder_map;
use fast32::base32::Alphabet32Nopad;

const ENC_CROCKFORD_LOWER: &'static [u8; 32] = b"0123456789abcdefghjkmnpqrstvwxyz";
const DEC_CROCKFORD_LOWER: [u8; 256] = decoder_map(
    ENC_CROCKFORD_LOWER,
    b"iloABCDEFGHIJKLMNOPQRSTVWXYZ",
    b"110abcdefgh1jk1mn0pqrstvwxyz",
);
pub const CROCKFORD_LOWER: Alphabet32Nopad = Alphabet32Nopad::new(ENC_CROCKFORD_LOWER, &DEC_CROCKFORD_LOWER);

assert_eq!(CROCKFORD_LOWER.encode_u64(31), "z");
assert_eq!(CROCKFORD_LOWER.decode_u64_str("z").unwrap(), 31);
