Struct DrmOutput 

pub struct DrmOutput { /* private fields */ }

A KMS output: a connector of a card, drawn with OpenGL.

Implementations

impl DrmOutput

pub fn new_with_mode_and_options( card: DrmCard, resources: &DrmResources, connector: &DrmConnector, mode_info: &DrmModeInfo, options: Option<DrmOutputOptions>, ) -> Result<Arc<Self>>

The output of a connector and a mode of the card that are already chosen, with options.

pub fn new( path: Option<&str>, connectors_force_probe: bool, options: Option<DrmOutputOptions>, ) -> Result<Arc<Self>>

Opens the card path (or the first usable card) and drives its first connected connector (of the options’ connector type and type identifier) in the options’ video mode or its preferred mode.

pub fn from_card( card: DrmCard, connectors_force_probe: bool, options: Option<DrmOutputOptions>, ) -> Result<Arc<Self>>

As new, on a card that is open.

pub fn new_with_mode( card: DrmCard, resources: &DrmResources, connector: &DrmConnector, mode_info: &DrmModeInfo, ) -> Result<Arc<Self>>

The output of a connector and a mode of the card that are already chosen, with the default options.

pub fn set_orientation(&self, value: SurfaceOrientation)

pub fn card(&self) -> &DrmCard

The card the output drives. An addition, for reading back what the card shows (drm_scanout).

pub fn crtc_id(&self) -> u32

The CRTC that shows the output. An addition, as card.

pub fn create_gl_render_target_of_primary_context( &self, ) -> Rc<dyn IGlPlatformSurfaceRenderTarget>

The render target over the output’s context (CreateGlRenderTarget()).

Panics

As IPlatformGraphics::get_shared_context of the output’s platform graphics: the call creates the EGL objects when this is the first.

pub fn create_context(&self) -> Rc<dyn IGlContext>

Panics

Always, as the reference (NotImplementedException).

Trait Implementations

impl IGlOutputBackend for DrmOutput

fn platform_graphics(&self) -> Arc<dyn IPlatformGraphics>

impl IGlPlatformSurface for DrmOutput

fn create_gl_render_target( &self, context: &Rc<dyn IGlContext>, ) -> Rc<dyn IGlPlatformSurfaceRenderTarget>

Panics

When context is not the context of the output (the exception of the reference).

impl IOutputBackend for DrmOutput

fn pixel_size(&self) -> PixelSize

fn scaling(&self) -> f64

fn set_scaling(&self, value: f64)

fn as_render_surface(self: Arc<Self>) -> Arc<dyn IPlatformRenderSurface>

The output as the render surface of the top-level.

fn as_gl_output_backend(&self) -> Option<&dyn IGlOutputBackend>

The output as one that renders with OpenGL (the reference tests the type).

fn as_surface_orientation(&self) -> Option<&dyn ISurfaceOrientation>

The output as one that has an orientation (the reference tests the type).

impl IPlatformRenderSurface for DrmOutput

fn try_get_surface_kind(&self, kind: TypeId) -> Option<Rc<dyn Any>>

The surface viewed as a surface kind defined outside this crate: for TypeId::of::<dyn IFoo>() the result holds an Rc<dyn IFoo>.

fn as_any(&self) -> &dyn Any

Lets the backend recover the concrete surface type.

fn is_ready(&self) -> bool

Whether the surface is ready to be rendered to.

fn as_framebuffer_surface(&self) -> Option<&dyn IFramebufferPlatformSurface>

The surface as a framebuffer surface, if it is one.

fn text_rendering_parameters(&self) -> Option<PlatformTextRenderingParameters>

The text rendering settings of the platform for this surface, when the platform knows them: the render backend asks for them every frame (they follow the settings of the system and the display the surface is on). A backend asks every surface of a top-level and takes the first answer; None from all of them gives the defaults of the backend (docs/porting/text-rendering.md).

impl ISurfaceOrientation for DrmOutput

fn orientation(&self) -> SurfaceOrientation
