Errors that can occur while rendering a solid offscreen.

Variants

NoAdapter(String)

No wgpu adapter could be obtained (neither a real GPU nor a software fallback). The crate is still usable on machines that do provide one.

DeviceRequest(String)

The adapter could not provide a device/queue matching the request.

BufferMap(String)

A GPU buffer could not be mapped for readback.

Poll(String)

Polling the device for readback completion failed.

InvalidSize

The requested render dimensions were invalid (zero width or height).

Fields

width: u32

Requested width in pixels.

height: u32

Requested height in pixels.

SizeTooLarge

The requested render dimensions exceed the adapter’s maximum 2D texture size, so a render would fail GPU validation.

Fields

width: u32

Requested width in pixels.

height: u32

Requested height in pixels.

max: u32

The adapter’s max_texture_dimension_2d.

MeshData(String)

The tessellation produced a mesh that violates a renderer invariant (e.g. an index buffer length not divisible by 3, an out-of-range vertex index, or grouped face offsets that do not cover every triangle).

EventLoop(String)

The windowing event loop could not be created or run (viewer only).

SurfaceConfig(String)

A window surface could not be created or configured (viewer only).

Operations(OperationsError)

Tessellation of the input solid failed.

Topology(TopologyError)

Topology traversal of the input solid failed.

Trait Implementations

impl Debug for RenderError

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

Formats the value using the given formatter.

impl Display for RenderError

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

Formats the value using the given formatter.

impl Error for RenderError

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<OperationsError> for RenderError

fn from(source: OperationsError) -> Self

Converts to this type from the input type.

impl From<TopologyError> for RenderError

fn from(source: TopologyError) -> Self

Converts to this type from the input type.
