[−]Struct epoll::Events
Methods
impl Events
pub const EPOLLET: Events
Sets the Edge Triggered behavior for the associated file descriptor.
The default behavior for epoll is Level Triggered.
pub const EPOLLIN: Events
The associated file is available for read operations.
pub const EPOLLERR: Events
Error condition happened on the associated file descriptor.
wait
will always wait for this event; is not necessary to set it in events.
pub const EPOLLHUP: Events
Hang up happened on the associated file descriptor.
wait
will always wait for this event; it is not necessary to set it in events.
Note that when reading from a channel such as a pipe or a stream socket, this event
merely indicates that the peer closed its end of the channel. Subsequent reads from
the channel will return 0 (end of file) only after all outstanding data in the
channel has been consumed.
pub const EPOLLOUT: Events
The associated file is available for write operations.
pub const EPOLLPRI: Events
There is urgent data available for read operations.
pub const EPOLLRDHUP: Events
Stream socket peer closed connection, or shut down writing half of connection.
This flag is especially useful for writing simple code to detect peer shutdown when using Edge Triggered monitoring.
pub const EPOLLWAKEUP: Events
If EPOLLONESHOT
and EPOLLET
are clear and the process has the CAP_BLOCK_SUSPEND
capability, ensure that the system does not enter "suspend" or "hibernate" while this
event is pending or being processed.
The event is considered as being "processed" from the time when it is returned by
a call to wait
until the next call to wait
on the same EpollInstance
descriptor, the closure of that file descriptor, the removal of the event file
descriptor with EPOLL_CTL_DEL
, or the clearing of EPOLLWAKEUP
for the event file
descriptor with EPOLL_CTL_MOD
.
pub const EPOLLONESHOT: Events
Sets the one-shot behavior for the associated file descriptor.
This means that after an event is pulled out with wait
the associated file
descriptor is internally disabled and no other events will be reported by the epoll
interface. The user must call ctl
with EPOLL_CTL_MOD
to rearm the file
descriptor with a new event mask.
pub fn empty() -> Events
Returns an empty set of flags.
pub fn all() -> Events
Returns the set containing all flags.
pub fn bits(&self) -> u32
Returns the raw value of the flags currently stored.
pub fn from_bits(bits: u32) -> Option<Events>
Convert from underlying bit representation, unless that representation contains bits that do not correspond to a flag.
pub fn from_bits_truncate(bits: u32) -> Events
Convert from underlying bit representation, dropping any bits that do not correspond to flags.
pub fn is_empty(&self) -> bool
Returns true
if no flags are currently stored.
pub fn is_all(&self) -> bool
Returns true
if all flags are currently set.
pub fn intersects(&self, other: Events) -> bool
Returns true
if there are flags common to both self
and other
.
pub fn contains(&self, other: Events) -> bool
Returns true
all of the flags in other
are contained within self
.
pub fn insert(&mut self, other: Events)
Inserts the specified flags in-place.
pub fn remove(&mut self, other: Events)
Removes the specified flags in-place.
pub fn toggle(&mut self, other: Events)
Toggles the specified flags in-place.
pub fn set(&mut self, other: Events, value: bool)
Inserts or removes the specified flags depending on the passed value.
