[calldelegation]

${txt} ${nonce}

Convert u64 to String for concatenation

EDIT/SOLUTION: the to_le_bytes() returns 8 bytes for num.to_le_bytes() which is totally fine and thus it might concatenate 8 symbols to the string which is not what we want. I tried several available built-in methods without any luck and came up with my own solution which works but might be unoptimal/not super efficient: fn convert_num_to_ascii_bytes(num: u64) -> Bytes { let mut bytes = Bytes::new(); let mut n = num; if n == 0 { bytes.push(48); return bytes; } …
