//! wiremock-multipart adds matchers for use with [wiremock](https://crates.io/crates/wiremock)
//! to check multipart characteristics of requests.
//!
//! ## How to install
//! Add `wiremock-multipart` to your dev-dependencies:
//! ```toml
//! [dev-dependencies]
//! # ...
//! wiremock-multipart = "0.1"
//! ```
//!
//! ## Getting started
//!
//! ```rust
//! use wiremock::{MockServer, Mock, ResponseTemplate};
//! use wiremock::matchers::method;
//! use wiremock_multipart::prelude::*;
//!
//! #[async_std::main]
//! async fn main() {
//!     // Start a background HTTP server on a random local port
//!     let mock_server = MockServer::start().await;
//!
//!     // Arrange the behaviour of the MockServer adding a Mock
//!     Mock::given(method("POST"))
//!         .and(NumberOfParts(2))
//!         .respond_with(ResponseTemplate::new(200))
//!         // Mounting the mock on the mock server - it's now effective!
//!         .mount(&mock_server)
//!         .await;
//!
//!     // if we now send a multipart/form-data request with two parts to it, the request
//!     // will match and return 200.
//! }
//! ```
