Struct PosixTimer

pub struct PosixTimer { /* private fields */ }

Posix Timer

When using c_wrapper feature implementation uses C shim to create timers which call callbacks from a separate thread.

Without it, callback is called from signal handler which limits usable operations within the callback.
