Crate rune_hex 

Hex encoding and decoding for byte slices and files.

Converts between raw bytes and their hexadecimal string representation. Decoding accepts mixed-case input and optional 0x prefix. The library has zero dependencies.

Features

• encode — encode bytes to a lowercase hex string.
• encode_upper — encode bytes to an uppercase hex string.
• decode — decode a hex string to bytes; accepts mixed case and 0x prefix.
• HexError — error type for malformed input.

Quick Start

use rune_hex::{encode, decode};

let hex = encode(b"hello");
assert_eq!(hex, "68656c6c6f");

let bytes = decode(&hex).unwrap();
assert_eq!(bytes, b"hello");

Enums

HexError

Error returned when decode encounters invalid hex input.
