Removed support for timerfd on Android as it seems to have been deprecated? See https://android.googlesource.com/platform/development/+/73a5a3b/ndk/platforms/android-20/include/sys/timerfd.h or https://github.com/rust-lang/libc/issues/1589 Removed the public status of `TimerSpec`, as it should not be exposed to the user. Implemented `FromRawFd` for `TimerFd` as it already implements `AsRawFd`. Addressed comments from the latest code review: - Removed upper bound assertions on timer expirations in tests. - Made the main example runnable and added code to show how to wait for the timer. - Refactored `ClockId` to use `libc_enum`. - Added comments for all public parts of the module. - Wrapped to 80 cols. - Changed the size of the buffer in the tests to the minimum required. * Ran rustfmt. * Added a `From` implementation for `libc::timespec` -> `TimeSpec`. * Reworked the example with the new changes and changed the timer from 5 to 1 second. * Added a constructor for a 0-initialized `TimerSpec`. * Added a new method to get the timer configured expiration (based on timerfd_gettime). * Added an helper method to unset the expiration of the timer. * Added a `wait` method to actually read from the timer. * Renamed `settime` into just `set`. * Refactored the tests and added a new one that tests both the `unset` and the `get` method. Modified CHANGELOG.
