A rust library for single instance application.
single-instance provides a single API to check if there are any other running instance.
Detail
On windows, init SingleInstance will create a mutex named by given &str then check error code by calling GetLastError.
On linux init will bind abstract unix domain socket with given name . On macos, init will create or open a file which path is given &str,
then call flock to apply an advisory lock on the open file.

extern crate single_instance;
use thread;
use SingleInstance;
