#![no_std]

//! # Introduction
//!
//! Library for parsing/editing/constructing SIP requests and responses.
//!
//! This is the very first version where only simple parsing is support.
//!
//! ## Example
//! ```rust
//!
//! use sipmsg::*;
//! use unicase::Ascii;
//!
//! let invite_msg_buf = "\
//! INVITE sip:bob@biloxi.com;user=phone?to=alice%40atlanta.com&priority=urgent SIP/2.0\r\n\
//! Via: SIP/2.0/UDP pc33.atlanta.com;branch=z9hG4bKkjshdyff\r\n\
//! Via: SIP/2.0/UDP 192.168.1.111\r\n\
//! To: Bob <sip:bob@biloxi.com>\r\n\
//! From: Alice <sip:alice@atlanta.com>;tag=88sja8x\r\n\
//! Contact: Caller <sip:alice@client.atlanta.example.com;transport=tcp>\r\n\
//! Max-Forwards: 70\r\n\
//! Call-ID: f81d4fae-7dec-11d0-a765-00a0c91e6bf6@foo.bar.com\r\n\
//! Extention-Header: extention header value;param=123;without_value\r\n\
//! CSeq: 986759 INVITE\r\n\r\nbody_stuff"
//! .as_bytes();
//!
//! // First parameter not realized yet.
//! // It should consist be residue if Content-Length is less then actual body length.
//! let (_, request) = SipRequest::parse(invite_msg_buf).unwrap();
//! assert_eq!(request.rl.method, SipMethod::INVITE);
