//! An asynchronously etcd client for Rust.
//!
//! etcd-rs supports etcd v3 API and async/await syntax.
//!
//! # Examples
//!
//! A simple key-value read and write operation:
//!
//! ```no_run
//! use etcd_rs::*;
//!
//! #[tokio::main]
//! async fn main() -> Result<()> {
//!     let client = Client::connect(ClientConfig {
//!         endpoints: vec!["http://127.0.0.1:2379".to_owned()],
//!         auth: None,
//!     }).await?;
//!
//!     let key = "foo";
//!     let value = "bar";
//!
//!     // Put a key-value pair
//!     let resp = client.kv().put(PutRequest::new(key, value)).await?;
//!
//!     println!("Put Response: {:?}", resp);
//!
//!     // Get the key-value pair
//!     let resp = client
//!         .kv()
//!         .range(RangeRequest::new(KeyRange::key(key)))
//!         .await?;
//!     println!("Range Response: {:?}", resp);
//!
//!     // Delete the key-valeu pair
//!     let resp = client
//!         .kv()
//!         .delete(DeleteRequest::new(KeyRange::key(key)))
//!         .await?;
//!     println!("Delete Response: {:?}", resp);
//!
//!    Ok(())
//! }
//! ```
