18//! Reqwest-based HTTP client implementation for reqsign.
19//!
20//! This crate provides `ReqwestHttpSend`, an HTTP client that implements
21//! the `HttpSend` trait from `reqsign_core` using the popular reqwest library.
22//!
23//! ## Overview
24//!
25//! `ReqwestHttpSend` enables reqsign to send HTTP requests using reqwest's
26//! powerful and feature-rich HTTP client. It handles the conversion between
27//! standard `http` types and reqwest's types seamlessly.
28//!
29//! ## Example
30//!
31//! ```no_run
32//! use reqsign_core::Context;
33//! use reqsign_http_send_reqwest::ReqwestHttpSend;
34//! use reqwest::Client;
35//!
36//! #[tokio::main]
37//! async fn main() {
38//!     // Use default client
39//!     let ctx = Context::new()
40//!         .with_http_send(ReqwestHttpSend::default());
41//!
42//!     // Or use a custom configured client
43//!     let client = Client::builder()
44//!         .timeout(std::time::Duration::from_secs(30))
45//!         .build()
46//!         .unwrap();
47//!
48//!     let ctx = Context::new()
49//!         .with_http_send(ReqwestHttpSend::new(client));
50//! }
51//! ```
52//!
53//! ## Usage with Service Signers
54//!
55//! ```no_run
56//! use reqsign_core::{Context, Signer};
57//! use reqsign_http_send_reqwest::ReqwestHttpSend;
58//! use bytes::Bytes;
59//!
60//! # async fn example() -> anyhow::Result<()> {
61//! // Create context with reqwest HTTP client
62//! let ctx = Context::new()
63//!     .with_http_send(ReqwestHttpSend::default());
64//!
65//! // The context can send HTTP requests
66//! let req = http::Request::builder()
67//!     .method("GET")
68//!     .uri("https://api.example.com")
69//!     .body(Bytes::new())?;
70//!
71//! let resp = ctx.http_send(req).await?;
72//! println!("Response status: {}", resp.status());
73//! # Ok(())
74//! # }
75//! ```
76//!
77//! ## Custom Client Configuration
78//!
79//! ```no_run
80//! use reqsign_http_send_reqwest::ReqwestHttpSend;
81//! use reqwest::Client;
82//! use std::time::Duration;
83//!
84//! // Configure reqwest client with custom settings
85//! let client = Client::builder()
86//!     .timeout(Duration::from_secs(60))
87//!     .pool_max_idle_per_host(10)
88//!     .user_agent("my-app/1.0")
89//!     .build()
90//!     .unwrap();
91//!
92//! // Use the custom client
93//! let http_send = ReqwestHttpSend::new(client);
94//! ```
