Struct nix::sys::event::KEvent

#[repr(C)]
pub struct KEvent { /* private fields */ }

Available on crate feature event only.

A kernel event queue. Used to notify a process of various asynchronous events.

Implementations

impl KEvent

pub fn new( ident: uintptr_t, filter: EventFilter, flags: EventFlag, fflags: FilterFlag, data: intptr_t, udata: intptr_t ) -> KEvent

Construct a new KEvent suitable for submission to the kernel via the changelist argument of Kqueue::kevent.

pub fn ident(&self) -> uintptr_t

Value used to identify this event. The exact interpretation is determined by the attached filter, but often is a raw file descriptor.

pub fn filter(&self) -> Result<EventFilter>

Identifies the kernel filter used to process this event.

Will only return an error if the kernel reports an event via a filter that is unknown to Nix.

pub fn flags(&self) -> EventFlag

Flags control what the kernel will do when this event is added with Kqueue::kevent.

pub fn fflags(&self) -> FilterFlag

Filter-specific flags.

pub fn data(&self) -> intptr_t

Filter-specific data value.

pub fn udata(&self) -> intptr_t

Opaque user-defined value passed through the kernel unchanged.

Trait Implementations

impl Clone for KEvent

fn clone(&self) -> KEvent

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for KEvent

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Hash for KEvent

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq<KEvent> for KEvent

fn eq(&self, other: &KEvent) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
