Expand description

Trait for looking up standard SIP headers from any key-value store.

Implementors provide sip_header_str() and get all typed accessors as default implementations.

§Example

use std::collections::HashMap;
use sip_header::{SipHeaderLookup, SipHeader};

let mut headers = HashMap::new();
headers.insert(
    "Call-Info".to_string(),
    "<urn:emergency:uid:callid:abc>;purpose=emergency-CallId".to_string(),
);

assert_eq!(
    headers.sip_header(SipHeader::CallInfo),
    Some("<urn:emergency:uid:callid:abc>;purpose=emergency-CallId"),
);

let ci = headers.call_info().unwrap().unwrap();
assert_eq!(ci.entries()[0].purpose(), Some("emergency-CallId"));
