fio-ioengine-sys

Rust bindings to fio's ioengine API. This enables writing custom I/O engine plugins in Rust. For an example of how to use it, refer to the hello-null which is a near 1-1 translation of fio's null I/O engine. There is also an example of how to debug an I/O engine in VSCode using launch.json. This is generally a bad practice to checkin editor specific configuration files, but this has been done to provide a good example of the correct usage.
