//! # Ferrostar
//!
//! Ferrostar is a modern SDK for building turn-by-turn navigation applications.
//!
//! See the [README on GitHub](https://github.com/stadiamaps/ferrostar) for the moment,
//! as this is still under extremely active development,
//! and proper documentation is still in flux.

// Helpers that are only exposed via the FFI interface.
//
// Most of these exist for convenience since the UDL understandably isn't implementing a
// full Rust type system and it would be a bunch of boilerplate to expose the foll objects.
// Instead we use top-level functions to return dynamic objects conforming to the trait.
