Signing API requests without effort.

---

Most API is simple. But they could be complicated when they are hidden from complex abstraction. `reqsign` bring the simple API back: build, sign, send.

## Quick Start

```rust
use anyhow::Result;
use reqsign::AwsConfig;
use reqsign::AwsLoader;
use reqsign::AwsV4Signer;
use reqwest::Client;
use reqwest::Request;
use reqwest::Url;

#[tokio::main]
async fn main() -> Result<()> {
    // Signer can load region and credentials from environment by default.
    let client = Client::new();
    let config = AwsConfig::default().from_profile().from_env();
    let loader = AwsLoader::new(client.clone(), config);
    let signer = AwsV4Signer::new("s3", "us-east-1");
    // Construct request
    let url = Url::parse("https://s3.amazonaws.com/testbucket")?;
    let mut req = reqwest::Request::new(http::Method::GET, url);
    // Signing request with Signer
    let credential = loader.load().await?.unwrap();
    signer.sign(&mut req, &credential)?;
    // Sending already signed request.
    let resp = client.execute(req).await?;
    println!("resp got status: {}", resp.status());
    Ok(())
}
```
