//! 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 enable
//! `dispatch_tree` to switch command matching from a linear scan to a
//! character-level trie.
//!
//! Run:
//! ```bash
//! cargo run --manifest-path examples/example-dispatch-tree/Cargo.toml --quiet -- cmd5
//! ```
//!
//! Output:
//! ```plaintext
//! It's works!
//! ```
//!
