pub struct EpollEventInterest {
    file_descriptor: i32,

Expand description

EpollEventInterest registers the file description information to an epoll instance during a successful epoll_ctl call. It also stores additional information needed to check and update readiness state for epoll_wait.

events and data field matches the epoll_event struct defined by the epoll_ctl man page. For more information see the man page:

https://man7.org/linux/man-pages/man2/epoll_ctl.2.html

Fields§

§file_descriptor: i32

The file descriptor value of the file description registered.

§events: u32

The events bitmask retrieved from epoll_event.

§data: u64

The data retrieved from epoll_event. libc’s data field in epoll_event can store integer or pointer, but only u64 is supported for now. https://man7.org/linux/man-pages/man3/epoll_event.3type.html

§ready_list: Rc<RefCell<BTreeMap<(FdId, i32), EpollEventInstance>>>

Ready list of the epoll instance under which this EpollEventInterest is registered.

§epfd: i32

The file descriptor value that this EpollEventInterest is registered under.
