Struct wayland_server::protocol::wl_callback::WlCallback

pub struct WlCallback { /* private fields */ }

callback object

Clients can handle the ‘done’ event to get notified when the related request is done.

Note, because wl_callback objects are created from multiple independent factory interfaces, the wl_callback interface is frozen at version 1.

This interface has no requests.

Implementations

impl WlCallback

pub fn done(&self, callback_data: u32)

done event

Notify the client when the related request is done.

Trait Implementations

impl Clone for WlCallback

fn clone(&self) -> WlCallback

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for WlCallback

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

Formats the value using the given formatter.

impl PartialEq<Weak<WlCallback>> for WlCallback

fn eq(&self, other: &Weak<WlCallback>) -> 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 PartialEq<WlCallback> for WlCallback

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