Struct DmabufState

pub struct DmabufState { /* private fields */ }

Available on crate feature wayland and Linux only.

A handler for zwp_linux_dmabuf_v1::ZwpLinuxDmabufV1

Implementations

impl DmabufState

pub fn new<D>(globals: &GlobalList, qh: &QueueHandle<D>) -> DmabufState

where D: Dispatch<ZwpLinuxDmabufV1, GlobalData> + 'static,

Bind zwp_linux_dmabuf_v1 global version 3 or 4, if it exists.

This does not fail if the global does not exist.

pub fn modifiers(&self) -> &[DmabufFormat]

Only populated in version <4

On version 4, use DmabufState::get_surface_feedback.

pub fn version(&self) -> Option<u32>

Supported protocol version, if any

pub fn create_params<D>( &self, qh: &QueueHandle<D>, ) -> Result<DmabufParams, GlobalError>

where D: Dispatch<ZwpLinuxBufferParamsV1, GlobalData> + 'static,

Create a params object for constructing a buffer

Errors if zwp_linux_dmabuf_v1 does not exist or has unsupported version. An application can then fallback to using shm buffers.

pub fn get_default_feedback<D>( &self, qh: &QueueHandle<D>, ) -> Result<ZwpLinuxDmabufFeedbackV1, GlobalError>

where D: Dispatch<ZwpLinuxDmabufFeedbackV1, DmabufFeedbackData> + 'static,

Get default dmabuf feedback. Requires version 4.

On version 3, use DmabufState::modifiers.

pub fn get_surface_feedback<D>( &self, surface: &WlSurface, qh: &QueueHandle<D>, ) -> Result<ZwpLinuxDmabufFeedbackV1, GlobalError>

where D: Dispatch<ZwpLinuxDmabufFeedbackV1, DmabufFeedbackData> + 'static,

Get default dmabuf feedback for given surface. Requires version 4.

On version 3, use DmabufState::modifiers.
