Struct wayland_client::protocol::wl_registry::WlRegistry

pub struct WlRegistry { /* private fields */ }

global registry object

The singleton global registry object. The server has a number of global objects that are available to all clients. These objects typically represent an actual object in the server (for example, an input device) or they are singleton objects that provide extension functionality.

When a client creates a registry object, the registry object will emit a global event for each global currently in the registry. Globals come and go as a result of device or monitor hotplugs, reconfiguration or other events, and the registry will send out global and global_remove events to keep the client up to date with the changes. To mark the end of the initial burst of events, the client can use the wl_display.sync request immediately after calling wl_display.get_registry.

A client can bind to a global object by using the bind request. This creates a client-side handle that lets the object emit events to the client and lets the client invoke requests on the object.

See also the Event enum for this interface.

Implementations

impl WlRegistry

pub fn bind<I: Proxy + 'static, U: Send + Sync + 'static, D: Dispatch<I, U> + 'static>(
    &self,
    name: u32,
    version: u32,
    qh: &QueueHandle<D>,
    udata: U
) -> I

bind an object to the display

Binds a new, client-created object to the server using the specified name as the identifier.

Trait Implementations

impl Clone for WlRegistry

fn clone(&self) -> WlRegistry

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for WlRegistry

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

Formats the value using the given formatter.

impl PartialEq<Weak<WlRegistry>> for WlRegistry

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

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