Enum MjEditError 

#[non_exhaustive]
pub enum MjEditError {
    AllocationFailed,
    InvalidUtf8Path,
    ParseFailed(String),
    CompileFailed(String),
    SaveFailed(String),
    NotFound,
    AlreadyExists,
    UnsupportedOperation,

    },
}

Errors that can occur in model-specification editing operations (MjSpec and related types).

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.

AllocationFailed

MuJoCo failed to allocate the requested model element.

InvalidUtf8Path

A filesystem path argument contains invalid UTF-8.

ParseFailed(String)

MuJoCo failed to parse the XML (or other format) input.

CompileFailed(String)

MuJoCo failed to compile the spec into a model.

SaveFailed(String)

MuJoCo failed to save the spec to XML.

NotFound

A referenced element (e.g. parent default class) was not found.

AlreadyExists

An element with the same name already exists.

UnsupportedOperation

This operation is not supported for the current element.

DeleteFailed(String)

MuJoCo returned an error while attempting to delete the element.

XmlBufferTooSmall

The output buffer passed to MjSpec::save_xml_string was too small to hold the XML.

required_size follows snprintf-style semantics: it is the number of bytes MuJoCo would write, not counting the NUL terminator. To retry successfully, pass a buffer of at least required_size + 1 bytes.

Fields

required_size: usize

Number of bytes MuJoCo would write (excluding the NUL terminator). Pass a buffer of at least required_size + 1 bytes to retry.

Trait Implementations

impl Clone for MjEditError

fn clone(&self) -> MjEditError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for MjEditError

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

Formats the value using the given formatter.

impl Display for MjEditError

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

Formats the value using the given formatter.

impl Error for MjEditError

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 MjEditError

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