Module dns_message_parser::rr
source · [−]Expand description
This module contains struct for resource records handling.
The RR enum represents an arbitrary resource record. Each type has a dedicated struct,
which has a variant in the RR enum. For example, the A struct represent an A record.
The Class enum represents the class field of the resource record.
The Type enum represents the type field of the resource record.
Yet there are some missing resource records and types
Example
use dns_message_parser::rr::{RR, A};
// Init A record
let a = A {
// The domain name of the A record
domain_name: "example.org".parse().unwrap(),
// The time to live of the A record
ttl: 1000,
// The address of the A record
ipv4_addr: "10.0.0.1".parse().unwrap(),
};
// Convert the resource record into a RR
let rr = RR::A(a);
// Encode the A record into bytes::BytesMut
let bytes = rr.encode().unwrap();
// Decode the A record into a RR enum
let rr = RR::decode(bytes.freeze()).unwrap();Modules
