Struct wayland_server::NewResource
source · pub struct NewResource<I: Interface> { /* private fields */ }
Expand description
A newly-created resource that needs implementation
Whenever a new wayland object is created, you will
receive it as a NewResource
. You then have to provide an
implementation for it, in order to process the incoming
events it may receive. Once this done you will be able
to use it as a regular Resource
.
Implementations are structs implementing the appropriate
variant of the Implementation
trait. They can also be
closures.

user_data: UD,
token: &DisplayToken
) -> Resource<I>where
F: FnMut(I::Request, Resource<I>) + 'static,
Dest: FnMut(Resource<I>) + 'static,
UD: 'static,
I::Request: MessageGroup<Map = ResourceMap>,
Implement this resource using given function and implementation data.
This method allows the implementation data to not be Send
, but requires for
safety that you provide a token to the event loop owning the proxy. As the token
is not Send
, this ensures you are implementing the resource from the same thread
as the event loop runs on.
** Panics **
This function will panic if you create several wayland displays and do not provide a token to the right one.
