Enum Request

#[non_exhaustive]
pub enum Request<'a> {
    Destroy,
    CreateParams {},
    GetDefaultFeedback {},
    GetSurfaceFeedback {
        surface: WlSurface,
    },
}

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.

Destroy

unbind the factory

Objects created through this interface, especially wl_buffers, will remain valid.

This is a destructor, once sent this object cannot be used any longer.

CreateParams

create a temporary object for buffer parameters

This temporary object is used to collect multiple dmabuf handles into a single batch to create a wl_buffer. It can only be used once and should be destroyed after a ‘created’ or ‘failed’ event has been received.

GetDefaultFeedback

get default feedback

This request creates a new wp_linux_dmabuf_feedback object not bound to a particular surface. This object will deliver feedback about dmabuf parameters to use if the client doesn’t support per-surface feedback (see get_surface_feedback).

Only available since version 4 of the interface

GetSurfaceFeedback

get feedback for a surface

This request creates a new wp_linux_dmabuf_feedback object for the specified wl_surface. This object will deliver feedback about dmabuf parameters to use for buffers attached to this surface.

If the surface is destroyed before the wp_linux_dmabuf_feedback object, the feedback object becomes inert.

Only available since version 4 of the interface
