Errors that can occur in MjModel operations.

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.

InvalidUtf8Path

A filesystem path argument contains invalid UTF-8.

LoadFailed(String)

MuJoCo failed to load the model from a file, string, or buffer.

SaveFailed(String)

MuJoCo failed to save the model XML.

AllocationFailed

MuJoCo failed to allocate the requested structure.

StateSliceLengthMismatch

The state source slice has the wrong length for the given spec.

Fields

expected: usize

Expected length.

got: usize

Actual length.

SpecNotSubset

The destination spec is not a subset of the source spec.

BufferTooSmall

A destination buffer is too small for the operation.

Fields

needed: usize

Minimum number of elements required.

available: usize

Actual number of elements available.

SignatureMismatch

Two model-signature-bound objects were created from different models.

Fields

source: u64

Model signature of the source object.

destination: u64

Model signature of the destination object.

VfsError(MjVfsError)

A virtual-file-system operation failed while loading a model from a string.

InvalidIndex(usize, usize)

The given index is invalid or out of range.

Trait Implementations

impl Clone for MjModelError

fn clone(&self) -> MjModelError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for MjModelError

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

Formats the value using the given formatter.

impl Display for MjModelError

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

Formats the value using the given formatter.

impl Error for MjModelError

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<MjVfsError> for MjModelError

fn from(e: MjVfsError) -> Self

Converts to this type from the input type.

impl PartialEq for MjModelError

fn eq(&self, other: &MjModelError) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
