//! A default, cross-platform backend.
//!
//! - On native platforms, it will use:
//!   - `backend::native::tokio` when the `tokio` feature is enabled.
//!   - `backend::native::async-std` when the `async-std` feature is
//!     enabled.
//!   - `backend::native::smol` when the `smol` feature is enabled.
//!   - `backend::native::thread_pool` otherwise.
//!
//! - On Wasm, it will use `backend::wasm::wasm_bindgen`.
