Function base16::encode_upper

pub fn encode_upper<T: ?Sized + AsRef<[u8]>>(input: &T) -> String

Encode bytes as base16, using upper case characters for nibbles between 10 and 15 (A through F).

This is equivalent to base16::encode_config(bytes, base16::EncodeUpper).

Example

assert_eq!(base16::encode_upper(b"Hello World"), "48656C6C6F20576F726C64");
assert_eq!(base16::encode_upper(&[0xff, 0xcc, 0xaa]), "FFCCAA");

Availability

This function is only available when the alloc feature is enabled, as it needs to produce a String.
