Function needletail::formats::parse_sequence_reader

pub fn parse_sequence_reader<F, R, T>(
    reader: R, 
    type_callback: T, 
    callback: F
) -> Result<(), ParseError> where
    F: for<'a> FnMut(SequenceRecord<'a>),
    R: Read,
    T: FnMut(&'static str), 

Opens a Read stream and parses the FASTX records out. Also takes a "type_callback" that gets called as soon as we determine if the records are FASTA or FASTQ. If a file starts with a gzip or other header, transparently decompress it.
