Struct wgpu::Adapter [−][src]
Handle to a physical graphics and/or compute device.
Adapters can be used to open a connection to the corresponding Device
on the host system by using Adapter::request_device
.
Does not have to be kept alive.
Implementations
impl Adapter
[src]
pub fn request_device(
&self,
desc: &DeviceDescriptor<'_>,
trace_path: Option<&Path>
) -> impl Future<Output = Result<(Device, Queue), RequestDeviceError>> + Send
[src]
&self,
desc: &DeviceDescriptor<'_>,
trace_path: Option<&Path>
) -> impl Future<Output = Result<(Device, Queue), RequestDeviceError>> + Send
Requests a connection to a physical device, creating a logical device.
Returns the Device
together with a Queue
that executes command buffers.
Arguments
desc
- Description of the features and limits requested from the given device.trace_path
- Can be used for API call tracing, if that feature is enabled inwgpu-core
.
Panics
- Features specified by
desc
are not supported by this adapter. - Unsafe features were requested but not enabled when requesting the adapter.
- Limits requested exceed the values provided by the adapter.
- Adapter does not support all features wgpu requires to safely operate.
pub fn get_swap_chain_preferred_format(
&self,
surface: &Surface
) -> TextureFormat
[src]
&self,
surface: &Surface
) -> TextureFormat
Returns an optimal texture format to use for the SwapChain
with this adapter.
pub fn features(&self) -> Features
[src]
List all features that are supported with this adapter.
Features must be explicitly requested in Adapter::request_device
in order
to use them.
pub fn limits(&self) -> Limits
[src]
List the "best" limits that are supported by this adapter.
Limits must be explicitly requested in Adapter::request_device
to set
the values that you are allowed to use.
pub fn get_timestamp_period(&self) -> f32
[src]
Gets the amount of nanoseconds each tick of a timestamp query represents.
Returns zero if timestamp queries are unsupported.
pub fn get_info(&self) -> AdapterInfo
[src]
Get info about the adapter itself.
pub fn get_texture_format_features(
&self,
format: TextureFormat
) -> TextureFormatFeatures
[src]
&self,
format: TextureFormat
) -> TextureFormatFeatures
Returns the features supported for a given texture format by this adapter.
Note that the WebGPU spec further restricts the available usages/features.
To disable these restrictions on a device, request the Features::TEXTURE_ADAPTER_SPECIFIC_FORMAT_FEATURES
feature.
