Enum wayland_client::protocol::wl_registry::Event

#[non_exhaustive]pub enum Event {
    Global {
        name: u32,
        interface: String,

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.

Global

announce global object

Notify the client of global objects.

The event notifies the client that a global object with the given name is now available, and it implements the given version of the given interface.

Fields of Global

name: u32interface: Stringversion: u32

GlobalRemove

announce removal of global object

Notify the client of removed global objects.

This event notifies the client that the global identified by name is no longer available. If the client bound to the global using the bind request, the client should now destroy that object.

The object remains valid and requests to the object will be ignored until the client destroys it, to avoid races between the global going away and a client sending a request to it.
