6/// # Extension Traits for SIP JSON Access
7///
8/// This module provides extension traits that enhance SIP types with JSON access capabilities.
9/// These traits make it easy to work with SIP messages in a JSON-like way, offering path-based
10/// and query-based access patterns.
11///
12/// ## Overview
13///
14/// There are two primary traits provided:
15///
16/// 1. `SipJsonExt` - A general-purpose extension trait for any serializable type,
17/// providing path and query access methods.
18///
19/// 2. `SipMessageJson` - A specialized trait for SIP message types, providing
20/// shorthand methods for common SIP header fields.
21///
22/// ## Example Usage
23///
24/// ```rust
25/// use rvoip_sip_core::prelude::*;
26/// use rvoip_sip_core::json::SipJsonExt;
27///
28/// # fn example() -> Option<()> {
29/// // Create a SIP request
30/// let request = RequestBuilder::invite("sip:bob@example.com").unwrap()
31/// .from("Alice", "sip:alice@example.com", Some("1928301774"))
32/// .to("Bob", "sip:bob@example.com", None)
33/// .build();
34///
35/// // Access header fields using path notation
36/// let from_display = request.path_str_or("headers.From.display_name", "Unknown");
37/// let from_tag = request.path_str_or("headers.From.params[0].Tag", "No Tag");
38///
39/// // Access all display names using a query
40/// let display_names = request.query("$..display_name");
41/// # Some(())
42/// # }
43/// ```
44///
45/// ## Path Syntax
46///
47/// The path syntax used in methods like `get_path` and `path_str` follows these rules:
48///
49/// - Dot notation to access fields: `headers.From.display_name`
50/// - Array indexing with brackets: `headers.Via[0]`
51/// - Combined access: `headers.From.params[0].Tag`
52///
53/// ## JSON Query Syntax
54///
55/// The query method supports a simplified JSONPath-like syntax:
56///
57/// - Root reference: `$`
58/// - Deep scan: `$..field` (finds all occurrences of `field` anywhere in the structure)
59/// - Array slicing: `array[start:end]`
60/// - Wildcards: `headers.*` (all fields in headers)
61///
62/// Extension trait for all types implementing Serialize/Deserialize.
63///
64/// This trait provides JSON access methods to any type that can be serialized/deserialized,
65/// making it easy to work with SIP messages in a JSON-like way.
66///
67/// # Examples
68///
69/// Basic path access:
70///
71/// ```
72/// # use rvoip_sip_core::prelude::*;
73/// # use rvoip_sip_core::json::SipJsonExt;
74/// # fn example() -> Option<()> {
75/// let request = RequestBuilder::invite("sip:bob@example.com").unwrap()
76/// .from("Alice", "sip:alice@example.com", Some("1928301774"))
77/// .build();
78///
79/// // Access fields with path notation
80/// let from_tag = request.path_str_or("headers.From.params[0].Tag", "unknown");
81/// println!("From tag: {}", from_tag);
82/// # Some(())
83/// # }
84/// ```
85///
86/// Query-based access:
87///
88/// ```
89/// # use rvoip_sip_core::prelude::*;
90/// # use rvoip_sip_core::json::SipJsonExt;
91/// # fn example() -> Option<()> {
92/// let request = RequestBuilder::invite("sip:bob@example.com").unwrap()
93/// .from("Alice", "sip:alice@example.com", Some("1928301774"))
94/// .build();
95///
96/// // Find all display names in the message
97/// let display_names = request.query("$..display_name");
98/// for name in display_names {
99/// println!("Found display name: {}", name);
100/// }
101/// # Some(())
102/// # }
103/// ```

1173/// Extension trait for SIP message types providing shortcuts for common headers.
1174///
1175/// This trait builds on `SipJsonExt` to provide convenient accessor methods
1176/// specifically for common SIP message headers.
1177///
1178/// # Examples
1179///
1180/// Basic header access:
1181///
1182/// ```rust
1183/// # use rvoip_sip_core::prelude::*;
1184/// # use rvoip_sip_core::json::ext::SipMessageJson;
1185/// # fn example() -> Option<()> {
1186/// let request = RequestBuilder::invite("sip:bob@example.com").unwrap()
1187/// .from("Alice", "sip:alice@example.com", Some("tag12345"))
1188/// .to("Bob", "sip:bob@example.com", None)
1189/// .build();
1190///
1191/// // Access common headers with convenience methods
1192/// let from_display = request.from_display_name()?;
1193/// let from_uri = request.from_uri()?;
1194/// let from_tag = request.from_tag()?;
1195/// let call_id = request.call_id()?;
1196///
1197/// println!("From: {} <{}>;tag={}", from_display, from_uri, from_tag);
1198/// println!("Call-ID: {}", call_id);
1199/// # Some(())
1200/// # }
1201/// ```
1202///
1203/// Working with multiple headers:
1204///
1205/// ```rust
1206/// # use rvoip_sip_core::prelude::*;
1207/// # use rvoip_sip_core::json::ext::SipMessageJson;
1208/// # fn example() -> Option<()> {
1209/// let request = RequestBuilder::invite("sip:bob@example.com").unwrap()
1210/// .from("Alice", "sip:alice@example.com", Some("tag1"))
1211/// .to("Bob", "sip:bob@example.com", Some("tag2"))
1212/// .via("proxy.example.com", "UDP", Some("z9hG4bK776asdhds"))
1213/// .build();
1214///
1215/// // Combine header accessors to build a formatted string
1216/// let from = format!("{} <{}>;tag={}",
1217/// request.from_display_name()?,
1218/// request.from_uri()?,
1219/// request.from_tag()?
1220/// );
1221///
1222/// // Access Via headers
1223/// let transport = request.via_transport()?;
1224/// let host = request.via_host()?;
1225/// let branch = request.via_branch()?;
1226///
1227/// println!("Via: SIP/2.0/{} {};branch={}", transport, host, branch);
1228/// # Some(())
1229/// # }
1230/// ```

1235 // fn from_uri(&self) -> Option<String>;
1236 // fn from_tag(&self) -> Option<String>;
1237 // etc.
