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 std::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();
}

bindings for gb-io's parser.
