Struct gfx_backend_empty::PhysicalDevice

pub struct PhysicalDevice;

Dummy physical device.

Trait Implementations

impl Debug for PhysicalDevice

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

Formats the value using the given formatter.

impl PhysicalDevice<Backend> for PhysicalDevice

unsafe fn open(
    &self,
    families: &[(&QueueFamily, &[QueuePriority])],
    _requested_features: Features
) -> Result<Gpu<Backend>, CreationError>

Create a new logical device with the requested features. If requested_features is empty, then only the core features are supported.

fn format_properties(&self, _: Option<Format>) -> Properties

Fetch details for a particular format.

fn image_format_properties(
    &self,
    _: Format,
    _dim: u8,
    _: Tiling,
    _: Usage,
    _: ViewCapabilities
) -> Option<FormatProperties>

Fetch details for a particular image format.

fn memory_properties(&self) -> MemoryProperties

Fetch details for the memory regions provided by the device.

fn external_buffer_properties(
    &self,
    _usage: Usage,
    _sparse: SparseFlags,
    _memory_type: ExternalMemoryType
) -> ExternalMemoryProperties

Get external buffer properties. The parameters specify how the buffer is going to used.

fn external_image_properties(
    &self,
    _format: Format,
    _dimensions: u8,
    _tiling: Tiling,
    _usage: Usage,
    _view_caps: ViewCapabilities,
    _memory_type: ExternalMemoryType
) -> Result<ExternalMemoryProperties, ExternalImagePropertiesError>

Get external image properties. The parameters specify how the image is going to used.

fn features(&self) -> Features

Returns the features of this PhysicalDevice. This usually depends on the graphics API being used, as well as the actual platform underneath.

fn properties(&self) -> PhysicalDeviceProperties

Returns the properties of this PhysicalDevice. Similarly to Features, they

unsafe fn enumerate_displays(&self) -> Vec<Display<Backend>>

Enumerate active displays surface from display. Please notice that, even if a system has displays attached, they could be not returned because they are managed by some other components. This function only return the display that are available to be managed by the current application. Since, generally, while compositor are running they take the control of every display connected, it could be better to run the application directly from the tty to avoid the return of an empty list.

unsafe fn enumerate_compatible_planes(
    &self,
    _display: &Display<Backend>
) -> Vec<Plane>

Enumerate compatibles planes with the provided display.

unsafe fn create_display_mode(
    &self,
    _display: &Display<Backend>,
    _resolution: (u32, u32),
    _refresh_rate: u32
) -> Result<DisplayMode<Backend>, DisplayModeError>

Create a new display mode from a display, a resolution, a refresh_rate and the plane index. If the builtin display modes does not satisfy the requirements, this function will try to create a new one.

unsafe fn create_display_plane<'a>(
    &self,
    _display: &'a DisplayMode<Backend>,
    _plane: &'a Plane
) -> Result<DisplayPlane<'a, Backend>, OutOfMemory>

Create a display plane from a display, a resolution, a refresh_rate and a plane. If the builtin display modes does not satisfy the requirements, this function will try to create a new one.

fn is_valid_cache(&self, _cache: &[u8]) -> bool

Check cache compatibility with the PhysicalDevice.
