Function odra_utils::hex_to_slice

pub fn hex_to_slice(src: &[u8], dst: &mut [u8])

Converts the hexadecimal values from the source byte slice into a more readable form, representing each byte in hexadecimal form, in the destination byte slice.

• It iterates over the source slice src and the destination slice dst concurrently.
• For each byte in the source, it calculates the hexadecimal representation.
• It splits the byte into two nibbles (4-bit groups): the higher order 4 bits and the lower order 4 bits.
• It converts each nibble into its corresponding hexadecimal representation.
• It stores the two hexadecimal representations in two consecutive slots of the destination slice.

Example

let mut dst = vec![0; 10];
let src = [255, 254, 253, 252, 251];
hex_to_slice(&src, &mut dst);
assert_eq!(&dst, &[102, 102, 102, 101, 102, 100, 102, 99, 102, 98]);
