dns-message-parser

A library to encode and decode DNS packets (RFC1035, RFC2535).

This library is not completed yet.

Usage

Add this to your Cargo.toml: toml [dependencies] dns-message-parser = "0.4"

Example

```rust use bytes::Bytes; use dnsmessageparser::{Dns, DomainName, Flags, Opcode, QClass, QType, Question, RCode}; use std::convert::TryFrom;

fn decode_example() { let msg = b"\xdb\x1c\x85\x80\x00\x01\x00\x01\x00\x00\x00\x00\x07\x65\x78\x61\x6d\x70\x6c\x65\ \x03\x6f\x72\x67\x00\x00\x01\x00\x01\xc0\x0c\x00\x01\x00\x01\x00\x00\x0e\x10\x00\x04\x0a\x00\ \x00\x0a";

let bytes = Bytes::copy_from_slice(&msg[..]);

let dns = Dns::decode(bytes).unwrap();
println!("{:?}", dns);

}

fn encodeexample() { let id = 56092; let flags = Flags { qr: true, opcode: Opcode::Query, aa: true, tc: false, rd: true, ra: true, ad: false, cd: false, rcode: RCode::NoError, }; let question = { let domainname = DomainName::tryfrom("example.org.").unwrap(); let qclass = QClass::IN; let q_type = QType::A;

    Question {
        domain_name,
        q_class,
        q_type,
    }
};

let questions = vec![question];
let dns = Dns {
    id,
    flags,
    questions,
    answers: Vec::new(),
    authorities: Vec::new(),
    additionals: Vec::new(),
};
let bytes = dns.encode().unwrap();
println!("{:?}", bytes);

} ```
