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:
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.

attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
