Crate mrt_rs

The mrt-rs crate provides functionality to parse an MRT-formatted streams.

Examples

Reading a MRT file containing BPG messages

use std::fs::File;
use std::io::Cursor;
use std::io::Read;
use std::io::BufReader;
use mrt_rs::{Reader, Record};
use mrt_rs::bgp4mp::BGP4MP;
use libflate::gzip::Decoder;

fn main() {
    // Open an MRT-formatted file.
    let file = File::open("res/updates.20190101.0000.gz").unwrap();

    // Decode the GZIP stream using BufReader for better performance.
    let mut decoder = Decoder::new(BufReader::new(file)).unwrap();

    // Create a new Reader with a Cursor such that we can keep track of the position.
    let mut reader = Reader { stream: decoder };

    // Keep reading entries till the end of the file has been reached.
    while let Ok(Some((header, record))) = reader.read() {
        match record {
            Record::BGP4MP(x) => match x {
                BGP4MP::MESSAGE(y) => println!("{:?}", y),
                BGP4MP::MESSAGE_AS4(y) => println!("{:?}", y),
                _ => continue,
            },
            _ => continue,
        }
    }
}
