Errors produced by the WebGL backend.

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.

Render(RenderError)

Rendering failed for a certain reason.

ContextUnavailable

A WebGL2 context could not be created for the canvas.

OperationFailed

A WebGL operation failed.

Fields

operation: WebGlOperation

The failed operation.

message: Option<String>

Additional diagnostic information, when available.

TooManyInstances

A render pass contains too many instances for WebGL.

ResourceTextureTooLarge

A resource texture allocation exceeds the supported texture dimensions.

Fields

width: u32

The requested texture width.

height: u32

The requested texture height.

max_dimension: u32

The maximum supported width or height.

IncompatibleContext(IncompatibleContextReason)

The WebGL context is incompatible with the renderer.

Trait Implementations

impl Clone for WebGlError

fn clone(&self) -> Self

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for WebGlError

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

Formats the value using the given formatter.

impl Display for WebGlError

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

Formats the value using the given formatter.

impl Error for WebGlError

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<RenderError> for WebGlError

fn from(source: RenderError) -> Self

Converts to this type from the input type.

impl From<WebGlError> for WebGlProbeError

fn from(source: WebGlError) -> Self

Converts to this type from the input type.
