Crate `hex`

Encoding and decoding hex strings.

For most cases, you can simply use the decode, encode and encode_upper functions. If you need a bit more control, use the traits ToHex and FromHex instead.

Example

# #[cfg(not(feature = "alloc"))]
# let mut output = [0; 0x18];
#
# #[cfg(not(feature = "alloc"))]
# hex::encode_to_slice(b"Hello world!", &mut output).unwrap();
#
# #[cfg(not(feature = "alloc"))]
# let hex_string = ::core::str::from_utf8(&output).unwrap();
#
# #[cfg(feature = "alloc")]
let hex_string = hex::encode("Hello world!");

println!("{}", hex_string); // Prints "48656c6c6f20776f726c6421"

# assert_eq!(hex_string, "48656c6c6f20776f726c6421");
