1//! Reqwest-based HTTP client implementation for reqsign.
2//!
3//! This crate provides `ReqwestHttpSend`, an HTTP client that implements
4//! the `HttpSend` trait from `reqsign_core` using the popular reqwest library.
5//!
6//! ## Overview
7//!
8//! `ReqwestHttpSend` enables reqsign to send HTTP requests using reqwest's
9//! powerful and feature-rich HTTP client. It handles the conversion between
10//! standard `http` types and reqwest's types seamlessly.
11//!
12//! ## Example
13//!
14//! ```no_run
15//! use reqsign_core::Context;
16//! use reqsign_http_send_reqwest::ReqwestHttpSend;
17//! use reqwest::Client;
18//!
19//! #[tokio::main]
20//! async fn main() {
21//!     // Use default client
22//!     let ctx = Context::new()
23//!         .with_http_send(ReqwestHttpSend::default());
24//!
25//!     // Or use a custom configured client
26//!     let client = Client::builder()
27//!         .timeout(std::time::Duration::from_secs(30))
28//!         .build()
29//!         .unwrap();
30//!
31//!     let ctx = Context::new()
32//!         .with_http_send(ReqwestHttpSend::new(client));
33//! }
34//! ```
35//!
36//! ## Usage with Service Signers
37//!
38//! ```no_run
39//! use reqsign_core::{Context, Signer};
40//! use reqsign_http_send_reqwest::ReqwestHttpSend;
41//! use bytes::Bytes;
42//!
43//! # async fn example() -> anyhow::Result<()> {
44//! // Create context with reqwest HTTP client
45//! let ctx = Context::new()
46//!     .with_http_send(ReqwestHttpSend::default());
47//!
48//! // The context can send HTTP requests
49//! let req = http::Request::builder()
50//!     .method("GET")
51//!     .uri("https://api.example.com")
52//!     .body(Bytes::new())?;
53//!
54//! let resp = ctx.http_send(req).await?;
55//! println!("Response status: {}", resp.status());
56//! # Ok(())
57//! # }
58//! ```
59//!
60//! ## Custom Client Configuration
61//!
62//! ```no_run
63//! use reqsign_http_send_reqwest::ReqwestHttpSend;
64//! use reqwest::Client;
65//! use std::time::Duration;
66//!
67//! // Configure reqwest client with custom settings
68//! let client = Client::builder()
69//!     .timeout(Duration::from_secs(60))
70//!     .pool_max_idle_per_host(10)
71//!     .user_agent("my-app/1.0")
72//!     .build()
73//!     .unwrap();
74//!
75//! // Use the custom client
76//! let http_send = ReqwestHttpSend::new(client);
77//! ```
