## Overview

The `reqwest-middleware` client exposes the same interface as a plain `reqwest` client, but
`ClientBuilder` exposes functionality to attach middleware:

```rust
use reqwest_middleware::{ClientBuilder, ClientWithMiddleware};
use reqwest_retry::{RetryTransientMiddleware, policies::ExponentialBackoff};
use reqwest_tracing::TracingMiddleware;

#[tokio::main]
async fn main() {
    let retry_policy = ExponentialBackoff::builder().build_with_max_retries(3);
    let client = ClientBuilder::new(reqwest::Client::new())
        .with(TracingMiddleware)
        .with(RetryTransientMiddleware::new_with_policy(retry_policy))
        .build();
    run(client).await;
}

async fn run(client: ClientWithMiddleware) {
    // free retries!
    client
        .get("https://some-external-service.com")
        .header("foo", "bar")
        .send()
        .await
        .unwrap();
}
```
