FastCGI implementation in pure Rust

FastCGI implementation in pure Rust.

The focus is on the webserver/client side, but the application/server side could be added in the future.

Developed for FlashRust Webserver with focus on

• Vectorized IO and Zero Copy
• async IO / tokio
• easy HTTP interfaces

Tested with:

• Flup (Python)
• PHP

cargo run --example webserver --features="con_pool"

Features

• Handle UnixStream and TCPStream transparently
• reconnect to the FCGI App if a connection is closed
• Start an FCGI server (exec + env)
• Support Key-Value Pairs bigger than maximum record size
• "Full Duplex" connection to the FCGI Server/App (e.g stream STDIN and OUT at the same time)
• con_pool should handle more than one connection 😅 and load balance
• A dropped FCGIBody should not block a RequestID and cancel the request
• Connection should handle overload error from FCGI app
• Parsing for FCGI application/server side

PullRequests are welcome BTW
