Error returned by the ucpack crate

Variants

BadVariant

Tried to serialize a variant index bigger than 255.

Eof

The cursor does not have any more data to deserialize from.

NoSupport(&'static str)

Serialization / Deserialization of this type is not supported by the ucpack protocol. If you think this is a mistake, please open an issue.

TooLong

Tried to serialize more than 256 bytes of payload data. This is a restriction imposed by the protocol.

BufferFull

Tried to serialize more bytes than the buffer could possible handle.

SerError(String)

DeError(String)

InvalidData

Input data for deserialization has problems finding a representation in a given data format

For example: a serialized boolean value ∉ {0, 1}

WrongCrc

Received a message with a wrong/faulty crc. Probably indicates data corruption.

WrongIndex

Received a message containing wrong index/indices for the start and stop bytes.

Trait Implementations

impl Debug for UcPackError

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

Formats the value using the given formatter.

impl Display for UcPackError

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

Formats the value using the given formatter.

impl Error for UcPackError

Available on crate feature std only.

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 Error for UcPackError

fn custom<T>(_msg: T) -> Self

where T: Display,

Used when a Serialize implementation encounters any error while serializing a type.

impl Error for UcPackError

fn custom<T>(_msg: T) -> Self

where T: Display,

Raised when there is general error when deserializing a type.

fn invalid_type(unexp: Unexpected<'_>, exp: &dyn Expected) -> Self

Raised when a Deserialize receives a type different from what it was expecting.

fn invalid_value(unexp: Unexpected<'_>, exp: &dyn Expected) -> Self

Raised when a Deserialize receives a value of the right type but that is wrong for some other reason.

fn invalid_length(len: usize, exp: &dyn Expected) -> Self

Raised when deserializing a sequence or map and the input data contains too many or too few elements.

fn unknown_variant(variant: &str, expected: &'static [&'static str]) -> Self

Raised when a Deserialize enum type received a variant with an unrecognized name.

fn unknown_field(field: &str, expected: &'static [&'static str]) -> Self

Raised when a Deserialize struct type received a field with an unrecognized name.

fn missing_field(field: &'static str) -> Self

Raised when a Deserialize struct type expected to receive a required field with a particular name but that field was not present in the input.

fn duplicate_field(field: &'static str) -> Self

Raised when a Deserialize struct type received more than one of the same field.
