Enum Error

pub enum Error {
    InvalidMarkerRead(Error),
    InvalidDataRead(Error),
    TypeMismatch(Marker),
    OutOfRange,
    LengthMismatch(u32),
    Uncategorized(String),

}

Enum representing errors that can occur while decoding MessagePack data.

Variants

InvalidMarkerRead(Error)

The enclosed I/O error occured while trying to read a MessagePack marker.

InvalidDataRead(Error)

The enclosed I/O error occured while trying to read the encoded MessagePack data.

TypeMismatch(Marker)

A mismatch occured between the decoded and expected value types.

OutOfRange

A numeric cast failed due to an out-of-range error.

LengthMismatch(u32)

A decoded array did not have the enclosed expected length.

Uncategorized(String)

An otherwise uncategorized error occured. See the enclosed String for details.

Syntax(String)

A general error occured while deserializing the expected type. See the enclosed String for details.

Utf8Error(Utf8Error)

An encoded string could not be parsed as UTF-8.

DepthLimitExceeded

The depth limit was exceeded; not currently used.

Trait Implementations

impl Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

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

Formats the value using the given formatter.

impl Error for Error

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 source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

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 Error

fn custom<T>(msg: T) -> Error

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.

impl<'a> From<DecodeStringError<'a>> for Error

fn from(err: DecodeStringError<'_>) -> Error

impl From<Utf8Error> for Error

fn from(err: Utf8Error) -> Error

Converts to this type from the input type.

impl From<ValueReadError> for Error

fn from(err: ValueReadError) -> Error

Converts to this type from the input type.
