//! Example Dispatch Tree
//!
//! > This example will introduce how to use `dispatch_tree`
//! > to optimize your command line lookup efficiency
//!
//! When the number of commands in your project increases, you can use `dispatch_tree` to complete command registration at compile time.
//! It will generate a trie for quickly finding related commands by prefix.
//!
//! Therefore, after enabling this feature,
//! `Program` will no longer store a Dispatcher list internally, and the `with_dispatcher` function will not be compiled.
//!
//! Run:
//! ```bash
//! cargo run --manifest-path examples/example-dispatch-tree/Cargo.toml --quiet -- cmd5
//! ```
//!
//! Output:
//! ```plaintext
//! It's works!
//! ```
//!
