//! Python bindings of `hg-core` objects using the `cpython` crate.

//! Once compiled, the resulting single shared library object can be placed in

//! the `mercurial` package directly as `rustext.so` or `rustext.dll`.

//! It holds several modules, so that from the point of view of Python,

//! it behaves as the `cext` package.

//!

//! Example:

//!

//! ```text

//! >>> from mercurial.rustext import ancestor

//! >>> ancestor.__doc__

//! 'Generic DAG ancestor algorithms - Rust implementation'

//! ```

/// This crate uses nested private macros, `extern crate` is still needed in

/// 2018 edition.
