SIMD-accelerated hex encoding and decoding.

Examples

use hex_simd::AsciiCase;

let bytes = b"Hello world!";

let encoded = hex_simd::encode_to_boxed_str(bytes, AsciiCase::Lower);
assert_eq!(&*encoded, "48656c6c6f20776f726c6421");

let decoded = hex_simd::decode_to_boxed_bytes(encoded.as_bytes()).unwrap();
assert_eq!(&*decoded, bytes);
