A caching middleware that follows HTTP caching rules,
thanks to [http-cache-semantics](https://github.com/kornelski/rusty-http-cache-semantics).
By default, it uses [cacache](https://github.com/zkat/cacache-rs) as the backend cache manager.
Uses [reqwest-middleware](https://github.com/TrueLayer/reqwest-middleware) for middleware support.

## Minimum Supported Rust Version (MSRV)

1.67.1

## Install

With [cargo add](https://github.com/killercup/cargo-edit#Installation) installed :

use reqwest::Client;
use reqwest_middleware::{ClientBuilder, Result};
use http_cache_reqwest::{Cache, CacheMode, CACacheManager, HttpCache, HttpCacheOptions};

#[tokio::main]
async fn main() -> Result<()> {
    let client = ClientBuilder::new(Client::new())
        .with(Cache(HttpCache {
          mode: CacheMode::Default,
          manager: CACacheManager::default(),
          options: HttpCacheOptions::default(),
        }))
        .build();
