Trait wayland_server::Handler

pub unsafe trait Handler<T: Resource> {
    unsafe fn message(&mut self,
                      evq: &mut EventLoopHandle,
                      client: &Client,
                      resource: &T,
                      opcode: u32,
                      args: *const wl_argument)
                      -> Result<(), ()>;
}

Generic handler trait

This trait is automatically implemented for objects that implement the appropriate interface-specific Handler traits. It represents the hability for a type to handle events directed to a given wayland interface.

For example, implementing wl_surface::Handler for you type will automatically provide it with an implementation of Handler<WlSurface> as well. This is the only correct way to implement this trait, and you should not attempt to implement it yourself.

Required Methods

                  args: *const wl_argument)
                  -> Result<(), ()>
