Errors returned by MotorCodec implementations.

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.

UnknownMotorType

The motor type is unknown to this vendor codec.

Fields

vendor: &'static str

Vendor short name.

type_id: u16

Opaque discriminant the codec did not recognize.

CommandNotSupported

The requested command mode is not implemented for the (codec, motor type) pair.

Fields

vendor: &'static str

Vendor short name.

mode: CommandKind

The command discriminant.

DecodeFailed

A recognized vendor frame could not be parsed (truncated payload, unsupported sub-protocol revision, etc.).

Fields

reason: &'static str

Human-readable explanation.

OutOfRange

A command field exceeds the motor’s published limit.

Fields

field: &'static str

Field name ("q", "dq", "tau", "kp", …).

Trait Implementations

impl Clone for CodecError

fn clone(&self) -> CodecError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CodecError

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

Formats the value using the given formatter.

impl Display for CodecError

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

Formats the value using the given formatter.

impl Error for CodecError

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<CodecError> for Error

fn from(source: CodecError) -> Self

Converts to this type from the input type.

impl PartialEq for CodecError

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