pub enum Error {
Show 15 variants BadLength, Overflow, ObjectNotFound, InvalidNodeId, ReadOnly, WriteOnly, TypeMismatch, DictionaryFull, UnsupportedTransfer, UnexpectedCommand, UnknownState, PdoTooLong, MappingFull, InvalidSyncCounter, ToggleMismatch,

Expand description

Errors surfaced by the canopen-rs core.

Variants (Non-exhaustive)§

This enum is marked as 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.
§

BadLength

A frame or buffer was too short or too long for the operation.

§

Overflow

A value did not fit the target CANopen data type.

§

ObjectNotFound

No object exists at the requested (index, subindex).

§

InvalidNodeId

A node id outside the valid 1..=127 range was supplied.

§

ReadOnly

Attempt to write an object that is not writable.

§

WriteOnly

Attempt to read an object that is not readable.

§

TypeMismatch

A value’s data type did not match the object’s data type.

§

DictionaryFull

The object dictionary’s fixed capacity is exhausted.

§

UnsupportedTransfer

The value cannot be carried by the chosen transfer (e.g. a value larger than four bytes attempted over expedited SDO).

§

UnexpectedCommand

A received frame’s command byte was not the expected response.

§

UnknownState

A heartbeat frame carried an unrecognised NMT state value.

§

PdoTooLong

A PDO’s mapped objects total more than eight bytes (64 bits).

§

MappingFull

A PDO mapping’s fixed capacity is exhausted.

§

InvalidSyncCounter

A SYNC counter overflow value outside 0 or 2..=240.

§

ToggleMismatch

An SDO segment’s toggle bit did not alternate as required.
