-//! ### Crossbeam-Channel & Tokio
-//!
-//! By default crossbeam-channel is used internally by notify. Which also allows the [Watcher] to be sync.
-//! This can [cause issues](https://github.com/notify-rs/notify/issues/380) when used inside tokio.
-//!
-//! You can disable crossbeam-channel, letting notify fallback to std channels via
-//!
-//! ```toml
-//! notify = { version = "6.1.1", default-features = false, features = ["macos_kqueue"] }
-//! // Alternatively macos_fsevent instead of macos_kqueue
-//! ```
-//! Note the `macos_kqueue` requirement here, otherwise no native backend is available on macos.
