//! Fastcgi client implemented for Rust.
//!
//! ![fastcgi-client-rs](https://raw.githubusercontent.com/jmjoy/fastcgi-client-rs/master/fastcgi-client-rs.png)
//!
//! ## Features
//!
//! Support both `async(async-std)` and `sync(std)` clients.
//!
//! Be default, both `async` and `sync` client are included, if you don't want to include `async` client,
//! You can specify `default-features = false` in `Cargo.toml`.
//!
//! ## Installation
//!
//! With [cargo add](https://github.com/killercup/cargo-edit) installed run:
//!
//! ```bash
//! $ cargo add fastcgi-client
//! ```
//!
//! ## Examples
//!
//! Async `async-std` client:
//!
//! ```
//! use fastcgi_client::{AsyncClient, Params};
//! use std::env;
//! use async_std::{io, task};
//! use async_std::net::TcpStream;
//!
//! task::block_on(async {
//!     let script_filename = env::current_dir()
//!         .unwrap()
//!         .join("tests")
//!         .join("php")
//!         .join("index.php");
//!     let script_filename = script_filename.to_str().unwrap();
//!     let script_name = "/index.php";
//!
//!     // Connect to php-fpm default listening address.
//!     let stream = TcpStream::connect(("127.0.0.1", 9000)).await.unwrap();
//!     let mut client = AsyncClient::new(stream, false);
//!
//!     // Fastcgi params, please reference to nginx-php-fpm config.
//!     let params = Params::with_predefine()
//!         .set_request_method("GET")
//!         .set_script_name(script_name)
//!         .set_script_filename(script_filename)
//!         .set_request_uri(script_name)
//!         .set_document_uri(script_name)
//!         .set_remote_addr("127.0.0.1")
//!         .set_remote_port("12345")
//!         .set_server_addr("127.0.0.1")
//!         .set_server_port("80")
//!         .set_server_name("jmjoy-pc")
//!         .set_content_type("")
//!         .set_content_length("0");
//!
//!     // Fetch fastcgi server(php-fpm) response.
//!     let output = client.do_request(&params, &mut io::empty()).await.unwrap();
//!
//!     // "Content-type: text/html; charset=UTF-8\r\n\r\nhello"
//!     let stdout = String::from_utf8(output.get_stdout().unwrap()).unwrap();
//!
//!     assert!(stdout.contains("Content-type: text/html; charset=UTF-8"));
//!     assert!(stdout.contains("hello"));
//!     assert_eq!(output.get_stderr(), None);
//! });
//! ```
//!
//! Sync `std` client:
//!
//! ```
//! use fastcgi_client::{Client, Params};
//! use std::{env, io};
//! use std::net::TcpStream;
//!
//! let script_filename = env::current_dir()
//!     .unwrap()
//!     .join("tests")
//!     .join("php")
//!     .join("index.php");
//! let script_filename = script_filename.to_str().unwrap();
//! let script_name = "/index.php";
//!
//! // Connect to php-fpm default listening address.
//! let stream = TcpStream::connect(("127.0.0.1", 9000)).unwrap();
//! let mut client = Client::new(stream, false);
//!
//! // Fastcgi params, please reference to nginx-php-fpm config.
//! let params = Params::with_predefine()
//!     .set_request_method("GET")
//!     .set_script_name(script_name)
//!     .set_script_filename(script_filename)
//!     .set_request_uri(script_name)
//!     .set_document_uri(script_name)
//!     .set_remote_addr("127.0.0.1")
//!     .set_remote_port("12345")
//!     .set_server_addr("127.0.0.1")
//!     .set_server_port("80")
//!     .set_server_name("jmjoy-pc")
//!     .set_content_type("")
//!     .set_content_length("0");
//!
//! // Fetch fastcgi server(php-fpm) response.
//! let output = client.do_request(&params, &mut io::empty()).unwrap();
//!
//! // "Content-type: text/html; charset=UTF-8\r\n\r\nhello"
//! let stdout = String::from_utf8(output.get_stdout().unwrap()).unwrap();
//!
//! assert!(stdout.contains("Content-type: text/html; charset=UTF-8"));
//! assert!(stdout.contains("hello"));
//! assert_eq!(output.get_stderr(), None);
