description	A high-performance file serving library. Serves files in special IO threads. In this version it uses normal file reading, but we will optimize using `sendfile` on supported systems as quick as tokio allows us to do that.

README

Sendfile for Tokio

:Status: alpha :Documentation: http://docs.rs/tk-sendfile

A thread pool that can process file requests and send data to the socket with zero copy (using sendfile).

Challenges:

While sendfile is non-blocking when writing to socket, it blocks for disk access for two cases: initial open() and for reading file inside the sendfile() system call itself
Doing more than single sendfile operation requires some bookkeeping
It should be possible to implement file cache (both opened files and in-memory file data) transparently for the user
[TODO] Serving user-specified file paths requires non-trivial code to prevent symlink attacks
