Function hex_string_upper 

pub fn hex_string_upper<const N: usize>(src: &[u8]) -> Result<String<N>, Error>

Available on crate feature heapless-08 only.

Encodes src as an uppercase hexadecimal string with inline capacity N.

This has the ownership and allocation-free behavior of hex_string, using A through F for letter digits. Capacity counts encoded characters.

Errors

Returns Error::Overflow or Error::OutputTooSmall under the same conditions as hex_string.

           "AB01");
