The description of a wayland interface

Implementations of this trait are supposed to be generated using the wayland-scanner crate.

Required Associated Constants

const NAME: &'static str

Name of this interface

const VERSION: u32

Maximum supported version of this interface

This is the maximum version supported by the protocol specification currently used by this library, and should not be used as-is in your code, as a version change can subtly change the behavior of some objects.

Server are supposed to be able to handle all versions from 1 to the one they advertise through the registry, and clients can choose any version among the ones the server supports.

Required Associated Types

type Request: MessageGroup + 'static

Set of requests associated to this interface

Requests are messages from the client to the server

type Event: MessageGroup + 'static

Set of events associated to this interface

Events are messages from the server to the client

Required Methods

fn c_interface() -> *const wl_interface

Pointer to the C representation of this interface

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
