#![cfg_attr(feature = "nightly", feature(never_type))]
#![warn(missing_docs)]

//! Hydroflow is a low-level dataflow-based runtime system for the [Hydro Project](https://hydro.run/).
//!
//! The primary item in this crate is the [`Hydroflow`](crate::scheduled::graph::Hydroflow) struct,
//! representing a Hydroflow dataflow graph. Although this graph can be manually constructed, the
//! easiest way to instantiate a `Hydroflow` instance is with the [`hydroflow_syntax!`] macro using
//! Hydroflow's custom "surface syntax."
//!
//! ```rust
//! let mut hf = hydroflow::hydroflow_syntax! {
//!     source_iter(["hello", "world"]) -> for_each(|s| println!("{}", s));
//! };
//! hf.run_available();
//! ```
//!
//! For more examples, check out the [`examples` folder on Github](https://github.com/hydro-project/hydroflow/tree/main/hydroflow/examples).
