Errors specific to the WebGPU backend.

Variants

NoAdapter

No compatible WebGPU adapter was found on this system.

DeviceRequest(String)

The device request to the adapter failed.

OutOfMemory

The GPU ran out of memory during buffer allocation.

ShaderCompilation(String)

WGSL shader source failed to compile.

PipelineCreation(String)

A compute pipeline could not be created.

NotInitialized

The backend has not been initialized yet.

Unsupported(String)

The requested operation is not supported by this backend.

InvalidArgument(String)

An invalid argument was passed to an operation.

BufferMapping(String)

A buffer mapping operation failed.

Timeout

An async operation timed out waiting for the adapter.

UncapturedError(String)

A wgpu validation, out-of-memory, or internal error was captured by the non-fatal on_uncaptured_error handler installed in crate::device::WebGpuDevice::new, instead of aborting the process (wgpu’s default handler is fatal). See crate::device::WebGpuDevice::poll_error.

DeviceLost(String)

The device was reported lost (GPU reset, driver failure, or an external Device::destroy() call) by the callback installed via Device::set_device_lost_callback in crate::device::WebGpuDevice::new.

Trait Implementations

impl Debug for WebGpuError

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

Formats the value using the given formatter.

impl Display for WebGpuError

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

Formats the value using the given formatter.

impl Error for WebGpuError

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0:

use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.

impl From<WebGpuError> for BackendError

fn from(e: WebGpuError) -> Self

Converts to this type from the input type.
