//! # context-coroutine
//!
//! Provides coroutines using the trait `Coroutine`.
//!
//! Coroutines use a separate, special stack.
//!
//! Implement this trait and then call `Coroutine::start_coroutine()`, passing in start arguments and a source of memory for the stack and heap.
//! Coroutines can use a switchable allocator, providing a straightforward way to restrict the amount of dynamic memory they can access and to ensure they only use thread-local memory.
//!
//! For a simple coroutine, use the stack `stacks::ProtectedStack`.
//!
//! This crate was originally a simple set of extensions to the [context](https://github.com/zonyitoo/context-rs) crate to provide stackful coroutines.
//! The developers are not associated with the authors of [context](https://github.com/zonyitoo/context-rs) but are extremely grateful for the work they've put into to a superb piece of code.
//!
//!
//! ## Licensing
//!
//! The license for this project is MIT.
