Struct dbus::ffidisp::Watch

pub struct Watch { /* private fields */ }

A file descriptor, and an indication whether it should be read from, written to, or both.

Implementations

impl Watch

pub fn fd(&self) -> WatchFd

Get the RawFd this Watch is for

pub fn readable(&self) -> bool

Add POLLIN to events to listen for

pub fn writable(&self) -> bool

Add POLLOUT to events to listen for

pub fn to_pollfd(&self) -> pollfd

Returns the current watch as a libc::pollfd, to use with libc::poll

Trait Implementations

impl AsRawFd for Watch

fn as_raw_fd(&self) -> RawFd

Extracts the raw file descriptor.

impl Clone for Watch

fn clone(&self) -> Watch

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Watch

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

Formats the value using the given formatter.

impl Ord for Watch

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

This method returns an Ordering between self and other.

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

Compares and returns the maximum of two values.

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

Compares and returns the minimum of two values.

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

Restrict a value to a certain interval.

impl PartialEq<Watch> for Watch

fn eq(&self, other: &Watch) -> 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<Watch> for Watch

fn partial_cmp(&self, other: &Watch) -> 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.
