//! A crate parsing common XMPP elements into Rust structures.
//!
//! Each module implements the `TryFrom<&minidom::Element>` trait, which takes
//! a minidom `Element` reference and returns a `Result`.
//!
//! Parsed structs can then be manipulated manually, and must be serialised
//! back before being sent over the wire.
