//! A wrapper library around `hotdrink-rs` for compilation to WebAssembly.
//!
//! # Prerequisites
//!
//! The project uses multiple nightly features, and must be built using nightly Rust.
//! I recommend using `rustup`, which can be downloaded [here](https://rustup.rs/),
//!
//! You also need `wasm-pack`, which can be downloaded [here](https://rustwasm.github.io/wasm-pack/installer/).
//!
//! The standard library must be recompiled, which means that we need the standard library source code.
//! This can be downloaded with `rustup component add rust-src`.
//!
//! # Build
//!
//! To use Web Workers from Rust, the we must compile with `--target no-modules`.
//! This should be as simple as running the following:
//!
//! ```bash
//! wasm-pack build --out-dir www/pkg --target no-modules --release
//! ```
//!
//! This will produce WebAssembly code and JS wrappers in www/pkg, which can then be imported there.
