Function seq_io::fasta::write_wrap_seq_iter

pub fn write_wrap_seq_iter<'a, W, S, L>(
    writer: W, 
    seq: S, 
    wrap: usize
) -> Result<()> where
    W: Write,
    S: IntoIterator<Item = L>,
    L: Borrow<[u8]>, 

Writes the sequence line from an iterator (such as SeqLines) and wraps the output to a maximum width specified by wrap.
