noodles-gff handles the reading and writing of the GFF3 format.

GFF (Generic Feature Format) is a text-based format used to represent genomic features.

Examples

Read all records in a GFF3 file

# use std::{fs::File, io::{self, BufReader}};
use noodles_gff as gff;

let mut reader = File::open("annotations.gff3")
    .map(BufReader::new)
    .map(gff::io::Reader::new)?;

for result in reader.record_bufs() {
    let record = result?;

    println!(
        "{}\t{}\t{}",
        record.reference_sequence_name(),
        record.start(),
        record.end(),
    );
}
# Ok::<(), io::Error>(())
