Enum MjViewerError 

#[non_exhaustive]
pub enum MjViewerError {
    EventLoopError(EventLoopError),
    GlutinError(Error),
    PainterInitError(String),
    GlInitFailed(GlInitError),
    SceneError(MjSceneError),
    ContextError(MjrContextError),
    SignatureMismatch,
    IndexOutOfBounds {

    },
}

Errors that can occur when initializing or running the MuJoCo viewer.

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.

EventLoopError(EventLoopError)

The event loop failed to initialize.

GlutinError(Error)

A glutin operation failed.

PainterInitError(String)

Returned when the egui painter (OpenGL UI renderer) fails to initialize.

GlInitFailed(GlInitError)

OpenGL / window initialization failed.

SceneError(MjSceneError)

A scene operation failed (e.g. user-scene sync overflowed the geom buffer).

ContextError(MjrContextError)

A rendering-context operation failed (e.g. a pixel-read buffer is too small or the viewport has invalid dimensions).

SignatureMismatch

The model’s structure signature does not match the viewer’s passive model. Call ViewerSharedState::sync_model or ViewerSharedState::sync_data first.

IndexOutOfBounds

The asset ID is out of range.

Fields

id: usize

The ID that was supplied.

len: usize

The number of assets in the model (the valid range is 0..len).

Trait Implementations

impl Debug for MjViewerError

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

Formats the value using the given formatter.

impl Display for MjViewerError

Formats a human-readable description of the viewer error.

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

Formats the value using the given formatter.

impl Error for MjViewerError

Provides the underlying error source, if any.

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.
