Function seq_io::fasta::write_iter

pub fn write_iter<W, H, S, L>(writer: W, head: H, seq: S) -> Result<()> where
    W: Write,
    H: HeadWriter,
    S: IntoIterator<Item = L>,
    L: Borrow<[u8]>, 

Helper function for writing data (not necessarily stored in a Record instance) to the FASTA format. In contrast to write, this function accepts a sequence iterator.
