Struct VringEpollHandler

pub struct VringEpollHandler<T: VhostUserBackend> { /* private fields */ }

Epoll event handler to manage and process epoll events for registered file descriptor.

The VringEpollHandler structure provides interfaces to:

• add file descriptors to be monitored by the epoll fd
• remove registered file descriptors from the epoll fd
• run the event loop to handle pending events on the epoll fd

Implementations

impl<T: VhostUserBackend> VringEpollHandler<T>

pub fn send_exit_event(&self)

Send exit event to break the event loop.

impl<T> VringEpollHandler<T>

where T: VhostUserBackend,

pub fn register_listener( &self, fd: RawFd, ev_type: EventSet, data: u64, ) -> Result<()>

Register an event into the epoll fd.

When this event is later triggered, the backend implementation of handle_event will be called.

pub fn unregister_listener( &self, fd: RawFd, ev_type: EventSet, data: u64, ) -> Result<()>

Unregister an event from the epoll fd.

If the event is triggered after this function has been called, the event will be silently dropped.

Trait Implementations

impl<T: VhostUserBackend> AsRawFd for VringEpollHandler<T>

fn as_raw_fd(&self) -> RawFd

Extracts the raw file descriptor.
