This is a library for parsing and working with Genbank (.gb) files written in Rust. It supports reading, writing, and extracting parts of a sequence while retaining feature annotations.

It should be able to handle most files out there. Feedback, improvements, and details of any .gb files it chokes on are welcome!

Reverse complement a sequence, retaining feature annotations.

extern crate gb_io;

use s
6CEA
td::fs::File;
use std::io;

use gb_io::reader::SeqReader;

fn main() {
    let file = File::open("mg1655.gb").unwrap();
    let stdout = io::stdout();
    for seq in SeqReader::new(file) {
        let seq = seq.unwrap();
        let rc = seq.revcomp();
        rc.write(stdout.lock()).unwrap();
    }
}

Martin Larralde has written Python bindings for gb-io's parser.
