* Default impl should block. Renaming it to avoid API confusion from previous users. * Can't get rid of libc::read because we have MaybeUninit, but we can clean up the match * Remove extra include * Switch everything over to io::Error * Add initial tokio impl+example * Move evtest_tokio to normal example * Add documentation and clarify * Use a VecDeque (ring buffer) instead of repeatedly popping things off the front of a Vec * Looks like we are not using thiserror anymore; removing * Store read buf between calls * Add nonblocking example with epoll Co-authored-by: Jeff Hiner <jeff-hiner@users.noreply.github.com> Co-authored-by: Noah <33094578+coolreader18@users.noreply.github.com>
