+//! # Coalesced
+//!
+//! Coalescion service to group, caching and queue duplicate actions.
+//! useful for deduplicating web requests, database lookups and other similar resource
+//! intensive or rate-limited actions.
+//!
+//! ## Features
+//! - `tokio`: Uses tokio for the async backend, this is currently the only backend.
+//! - `queue`: Whether to support queueing requests to only allow X amount of actions running at once.
+//! - `cache`: Whether to cache the actions results for future actions with the same id, uses an LRU cache internally.
+//!
+//! [`CoalescionService`] uses both [`Arc`] and [`RwLock`] internally and can be cheaply cloned to
+//! use in your codebase.
+//!
+//! It is common practice to wrap the service and in your own which delegates the executions to ensure all ids are tracked in one location across your codebase.
+//!
+//! All values are stored using [`Any`] and must be [`'static`] + [`Send`] + [`Sync`], if there is an id mismatch
+//! and a type is wrong the library will return an error, values returned from the service are also
+//! wrapped in an [`Arc`] as they are shared to each duplicate action.
+//!
+//! ## Example:
+//! ```rs
+//! use revolt_coalesced::CoalescionService;
+//!
+//! let service = CoalescionService::new();
+//!
+//! let user_id = "my_user_id";
+//! let user = service.execute(user_id, || async move {
+//!     database.fetch_user(user_id).await.unwrap()
+//! }).await;
+//! ```
