Crate tk_sendfile

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

Use DiskPool structure to request file operations.

Example

    let pool = DiskPool::new(CpuPool::new(40));
    pool.send("file", socket)

Settings

It’s recommended to make large number of threads in the pool for three reasons:

1. To make use of device parallelism
2. To allow kernel to merge some disk operations
3. To fix head of line blocking when some request reach disk but others could be served immediately from cache (we don’t know which ones are cached, so we run all of them in a pool)

FileOpener

This trait represents anything that can open the file

FileReader

This trait represents file that can atomically be read at specific point

IntoFileOpener
