Subject: Potential Solution to drop clippy errors

Calling the write!, the result that it returns doesn't matter or wasn't
deemed as important and was dropped before. This was just removed and
then the unused Result is ignored via clippy attribute. This is a
plausible solution to get past the Clippy Error, but others may be more
ideal.
