Errors that can occur during frame import or synchronization.

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.

Unsupported(UnsupportedReason)

The requested interop path is not supported for the given reason.

BackendMismatch

The wgpu backend on the host device does not match what the frame source requires.

Fields

expected: &'static str

actual: &'static str

InvalidFrame(&'static str)

The frame data is invalid (e.g. a zero-valued FBO id).

UnsupportedSynchronization(SyncMechanism)

The synchronizer received a SyncMechanism it does not handle.

Surfman(String)

A surfman-level error occurred while preparing the frame.

Vulkan(String)

A Vulkan API call failed during import.

Metal(String)

A Metal API call failed during import.

OpenGl(String)

A GL API call failed during import.

Dx12(String)

A D3D12 or DXGI API call failed during import.

Angle(String)

An ANGLE EGL API call failed during D3D11 share-handle import.

Trait Implementations

impl Debug for InteropError

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

Formats the value using the given formatter.

impl Display for InteropError

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

Formats the value using the given formatter.

impl Error for InteropError

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.
