Struct MasterRef

pub struct MasterRef<'a, T>(/* private fields */)
where
    T: 'a + Device;

A simple handle to the DRM Master lock. This can be generated by any object that implements the UnprivilegedDevice trait.

Trait Implementations

impl<'a, T> AsRawFd for MasterRef<'a, T>

where T: 'a + Device,

fn as_raw_fd(&self) -> RawFd

Extracts the raw file descriptor.

impl<'a, T> Control for MasterRef<'a, T>

where T: 'a + Device,

fn resource_ids(&self) -> Result<ResourceIds>

Attempts to read the list of all resource ids.

fn plane_ids(&self) -> Result<PlaneResourceIds>

Attempts to read the list of all plane ids.

fn connector(&self, id: ConnectorId) -> Result<ConnectorInfo>

Attempts to get a connector given its id.

fn encoder(&self, id: EncoderId) -> Result<EncoderInfo>

Attempts to get an encoder given its id.

fn crtc(&self, id: CrtcId) -> Result<CrtcInfo>

Attempts to get a crtc given its id.

fn framebuffer(&self, id: FramebufferId) -> Result<FramebufferInfo>

Attempts to get a framebuffer given its id.

fn plane(&self, id: PlaneId) -> Result<PlaneInfo>

Attempts to get a plane given its id.

fn create_framebuffer<T>(&self, buffer: &T) -> Result<FramebufferId>

where T: Buffer,

Attempts to get a Crtc’s Gamma Lookup Table (LUT) given its CrtcId.

fn add_framebuffer2(&self)

fn remove_framebuffer(&self, id: FramebufferId) -> Result<()>

fn dumbbuffer<'a>( &'a self, size: (u16, u16), bpp: u8, ) -> Result<DumbBuffer<'a, Self>>

fn properties<T>(&self, resource: T) -> Result<ResourcePropertyHandles>

where T: ResourceId,

fn resource_property( &self, handle: PropertyHandle, ) -> Result<ResourcePropertyInfo>

fn proberty_blob(&self)

fn create_property_blob(&self)

impl<'a, T> Debug for MasterRef<'a, T>

where T: 'a + Device + Debug,

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<'a, T> Device for MasterRef<'a, T>

where T: 'a + Device,

fn magic(&self) -> Result<AuthToken>

Generates and returns a magic token unique to the current process. This token can be used to authenticate with the DRM Master.

fn stats(&self) -> Result<()>

fn set_client_cap(&self, cap: ClientCapability, set: bool) -> Result<()>

Tells the DRM device whether we understand or do not understand a particular capability. Some features, such as atomic modesetting, require informing the device that the process can use such features before it will expose them.

fn wait_vblan(&self)

impl<'a, T> MasterControl for MasterRef<'a, T>

where T: 'a + Device,

fn set_crtc( &self, crtc: CrtcId, buffer: FramebufferId, connectors: &[ConnectorId], position: (u32, u32), mode: Option<Mode>, ) -> Result<()>

Applies a Crtc to a Framebuffer and outputs it on a list of Connectors.

impl<'a, T> MasterDevice for MasterRef<'a, T>

where T: 'a + Device,

fn drop_master(&self) -> Result<()>
