Struct epoll::EpollInstance

pub struct EpollInstance {
    // some fields omitted
}

Thread safe abstraction around the returned fd from libc::epoll_create(1)

Methods

impl EpollInstance

fn new() -> Result<EpollInstance>

Creates a new EpollInstance.

Notes

• FD_CLOEXEC flag is set on the underlying fd returned.

fn add_interest(&mut self, interest: Interest) -> Result<()>

Register an initial Interest with this instance.

Panics

Panics if the interior Mutex has been poisoned.

fn mod_interest(&mut self, interest: &Interest) -> Result<()>

Modify the original Interest, identified by its RawFd, to the passed interest's events and data fields.

Panics

Panics if the interior Mutex has been poisoned.

fn del_interest(&mut self, interest: &Interest) -> Result<()>

Remove the passed Interest, identified by its RawFd, from this instance.

Panics

Panics if the interior Mutex has been poisoned.

fn wait(&mut self, timeout: i32, max_returned: usize) -> Result<Vec<Interest>>

Waits for events on this instance for at most timeout milliseconds and returns at most max_returned Interests.

Notes

• If timeout is negative, it will block until an event is received.
• max_returned must be greater than zero.

Panics

Panics if the interior Mutex has been poisoned.

fn events(&self) -> u64

Returns the total number of events reported.

fn wait_time(&self) -> Duration

Returns the total time spent in a blocked, waiting state.
