//! Request and response module for fetching bounces for a domain.
//!
//! ### Example
//!
//! ```no_run
//! # use mailgun_sdk::{
//! #     Client,
//! #     ParamList,
//! #     get_bounces::{GetBouncesParam, GetBouncesParamList},
//! # };
//! # let client = Client::new("", "");
//! let request = GetBouncesParamList::default()
//!     .add(GetBouncesParam::Limit(1));
//!
//! let bounces = client.get_bounces(request).unwrap();
//! ```
