Struct Adapter 

pub struct Adapter { /* private fields */ }

Available on gles only.

Implementations

impl Adapter

pub unsafe fn new_external( webgl2_context: WebGl2RenderingContext, options: GlBackendOptions, ) -> Option<ExposedAdapter<Api>>

Available on webgl only.

Creates a new external adapter from an existing WebGL2 rendering context.

Safety

• The underlying WebGL2 context must be valid (not lost).
• The underlying WebGL2 context must be valid when interfacing with any objects returned by wgpu-hal from this adapter.
• The underlying WebGL2 context must be valid when dropping this adapter and when dropping any objects returned from this adapter.

pub fn adapter_context(&self) -> &AdapterContext

Available on webgl only.

impl Adapter

pub fn get_glsl_version(&self) -> Version

Trait Implementations

impl Adapter for Adapter

type A = Api

unsafe fn open( &self, features: Features, _limits: &Limits, _memory_hints: &MemoryHints, ) -> Result<OpenDevice<Api>, DeviceError>

unsafe fn texture_format_capabilities( &self, format: TextureFormat, ) -> TextureFormatCapabilities

Return the set of supported capabilities for a texture format.

unsafe fn surface_capabilities( &self, surface: &Surface, ) -> Option<SurfaceCapabilities>

Returns the capabilities of working with a specified surface.

unsafe fn get_presentation_timestamp(&self) -> PresentationTimestamp

Creates a PresentationTimestamp using the adapter’s WSI.

fn get_ordered_buffer_usages(&self) -> BufferUses

The combination of all usages that the are guaranteed to be be ordered by the hardware. If a usage is ordered, then if the buffer state doesn’t change between draw calls, there are no barriers needed for synchronization.

fn get_ordered_texture_usages(&self) -> TextureUses

The combination of all usages that the are guaranteed to be be ordered by the hardware. If a usage is ordered, then if the buffer state doesn’t change between draw calls, there are no barriers needed for synchronization.

unsafe fn surface_display_hdr_info( &self, surface: &<Self::A as Api>::Surface, ) -> Option<DisplayHdrInfo>

Returns the HDR / luminance characteristics of the display backing surface, queried from the OS on each call.

impl Debug for Adapter

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

Formats the value using the given formatter.

impl DynResource for Adapter

fn as_any(&self) -> &dyn Any

fn as_any_mut(&mut self) -> &mut dyn Any
