Available on crate feature alloc only.

Encodes data as hex string using uppercase characters.

Apart from the characters’ casing, this works exactly like encode().

Example

assert_eq!(hex::encode_upper("Hello world!"), "48656C6C6F20776F726C6421");
assert_eq!(hex::encode_upper(vec![1, 2, 3, 15, 16]), "0102030F10");
