Available on crate feature event only.

Kqueue filter types. These are all the different types of event that a kqueue can notify for.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

EVFILT_AIO = -3

Notifies on the completion of a POSIX AIO operation.

EVFILT_FS = -9

Establishes a file system monitor.

EVFILT_MACHPORT = -8

Mach portsets

EVFILT_PROC = -5

Notifies when a process performs one or more of the requested events.

EVFILT_READ = -1

Takes a file descriptor as the identifier, and notifies whenever there is data available to read.

EVFILT_SIGNAL = -6

Takes a signal number to monitor as the identifier and notifies when the given signal is delivered to the process.

EVFILT_TIMER = -7

Establishes a timer and notifies when the timer expires.

EVFILT_USER = -10

Notifies only when explicitly requested by the user.

EVFILT_VM = -12

Virtual memory events

EVFILT_VNODE = -4

Notifies when a requested event happens on a specified file.

EVFILT_WRITE = -2

Takes a file descriptor as the identifier, and notifies whenever it is possible to write to the file without blocking.

Trait Implementations

impl Clone for EventFilter

fn clone(&self) -> EventFilter

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for EventFilter

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

Formats the value using the given formatter.

impl Hash for EventFilter

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 Ord for EventFilter

fn cmp(&self, other: &EventFilter) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized + PartialOrd,

Restrict a value to a certain interval.

impl PartialEq for EventFilter

fn eq(&self, other: &EventFilter) -> 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.

impl PartialOrd for EventFilter

fn partial_cmp(&self, other: &EventFilter) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

This method tests less than (for self and other) and is used by the < operator.

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

This method tests less than or equal to (for self and other) and is used by the <= operator.

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

This method tests greater than (for self and other) and is used by the > operator.

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

This method tests greater than or equal to (for self and other) and is used by the >= operator.

impl TryFrom<i16> for EventFilter

type Error = Errno

The type returned in the event of a conversion error.

fn try_from(x: i16) -> Result<Self>

Performs the conversion.
