//! 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
//! ```rust
//! use dns_message_parser::rr::{RR, A};
//! use std::convert::TryInto;
//!
//! // Init A record
//! let a = A {
//!     // The domain name of the A record
//!     domain_name: "example.org".try_into().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();
//! ```
//!
//! [A]: crate::rr::A
//! [RR]: crate::rr::RR
//! [Class]: crate::rr::Class
//! [Type]: crate::rr::Type
//! [resource records]: https://tools.ietf.org/html/rfc1035#section-3.2
//! [class]: https://tools.ietf.org/html/rfc1035#section-3.2.4
//! [type]: https://tools.ietf.org/html/rfc1035#section-3.2.2
