pub fn unescape(cell: &[u8], quote: u8) -> Cow<'_, [u8]>Expand description
Unescape a potentially escaped but unquoted (no leading/trailing quotes) CSV cell.
Returns a Cow::Borrowed if nothing needed unescaping, and a
Cow::Owned if something was actually unescaped.
This function will therefore not allocate if this is not actually required.
