Everything that can go wrong opening or driving a device.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

NoAdapter

No adapter satisfied the device request.

Fields

detail: String

Backend selection diagnostics supplied by the active HAL.

SurfaceCreation

A window or canvas could not be converted into a presentation surface.

Fields

detail: String

Backend-reported creation failure.

DeviceRequest

An adapter was found but opening its logical device failed.

Fields

detail: String

Backend-reported device negotiation failure.

DeviceLost

The device was lost; recreate and retry.

Surface(SurfaceError)

The presentation surface is unavailable; reconfigure and skip the frame.

Capability

A requested capability is unavailable and no fallback applies.

Fields

name: &'static str

The capability that was required.

LimitExceeded

A requested resource exceeds a reported portable device limit.

Fields

resource: &'static str

Resource class that exceeded the limit.

limit: u64

Reported device ceiling.

ShaderCompile

A shader failed to compile on this backend.

Fields

label: String

Which shader module.

detail: String

Backend-reported detail, including stage and location where available.

Runtime

A GPU operation failed validation or exhausted backend resources.

Fields

detail: String

The first backend diagnostic, retained before secondary failures.

Implementations

impl GpuError

pub fn code(&self) -> &'static str

The stable registry code for this condition.

Trait Implementations

impl Debug for GpuError

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

Formats the value using the given formatter.

impl Display for GpuError

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

Formats the value using the given formatter.

impl Error for GpuError

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<SurfaceError> for GpuError

fn from(source: SurfaceError) -> Self

Converts to this type from the input type.
