Errors that can occur in MjData physics data and Jacobian 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.

IndexOutOfBounds

A provided object or body index was out of the valid range.

Fields

kind: &'static str

Name of the index parameter, e.g. "body_id" or "geom_id".

id: usize

The index value that was passed.

upper: usize

Exclusive upper bound of the valid range.

UnsupportedObjectType(i32)

The provided MuJoCo object type is not supported by this operation.

Contains the raw MuJoCo C object-type code (mjOBJ_*) that was not recognized.

AllocationFailed

MuJoCo failed to allocate the requested structure.

BufferTooSmall

A buffer passed to the operation is too small for the required data.

Fields

name: &'static str

Descriptive name of the buffer (e.g. "destination", "rgb").

got: usize

Actual length of the buffer that was provided.

needed: usize

Minimum length the buffer must have.

LengthMismatch

A slice or array parameter has the wrong length for the operation.

Fields

name: &'static str

Descriptive name of the parameter.

expected: usize

Expected length.

got: usize

Actual length that was provided.

SignatureMismatch

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

This is returned by APIs that require matching model signatures, including data-copy operations and info-view accessors.

Fields

source: u64

Model signature of the source object.

destination: u64

Model signature of the destination object.

NoHistoryBuffer

The specified actuator or sensor has no associated history buffer.

Fields

kind: &'static str

"actuator" or "sensor".

id: usize

The zero-based index of the actuator or sensor.

ContactBufferFull

The contact buffer is full; no more contacts can be added.

InvalidUtf8Path

A filesystem path argument contains invalid UTF-8.

Trait Implementations

impl Clone for MjDataError

fn clone(&self) -> MjDataError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for MjDataError

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

Formats the value using the given formatter.

impl Display for MjDataError

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

Formats the value using the given formatter.

impl Eq for MjDataError

impl Error for MjDataError

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 PartialEq for MjDataError

fn eq(&self, other: &MjDataError) -> 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.
