//! A crate parsing common XMPP elements into Rust structures.
|
|
//!
|
|
//! The main entrypoint is `parse_message_payload`, it takes a minidom
|
|
//! `Element` reference and optionally returns `Some(MessagePayload)` if the
|
|
//! parsing succeeded.
|
|
//!
|
|
//! Parsed structs can then be manipulated internally, and serialised back
|
|
//! before being sent over the wire.
