//! `spawns-compat` provides functions to find async runtimes for spawning task.
//!
//! It uses [linkme] to inject these functions to `spawns-core`. In some platforms, this crate may
//! not be linked to binary finally. So, you may have to speak explicitly about this with `extern
//! crate spawns_compat`. You could also use it with `spawns-core` through `spawns` which does so
//! for you. Besides this, in macOS, you may have to put below to your `Cargo.toml`.
//!
//! ```toml
//! [profile.dev]
//! lto = "thin"
//! ```
//!
//! See for details:
