1//! Simple Cursor on Target (CoT) (de)serialization library.
2//!
3//! Provides struct definitions and utilities which use
4//! [quick_xml](https://github.com/tafia/quick-xml) to handle conversion to/from XML text.
5//!
6//! The CoT base schema is represented by the [base::Cot] struct. You can either provide your own
7//! type for the detail section of the CoT message, or you can use [detail::parse()] to skip
8//! parsing the section and instead get raw XML text. What we really want is a dynamic type,
9//! analogous to [serde_json::Value](https://docs.rs/serde_json/latest/serde_json/enum.Value.html),
10//! but I haven't found anything similar for XML.
