Enum ErrorKind

pub enum ErrorKind {
    Io(Error),
    InvalidUtf8Encoding(Utf8Error),
    InvalidBoolEncoding(u8),
    InvalidCharEncoding,
    InvalidTagEncoding(usize),
    DeserializeAnyNotSupported,
    SizeLimit,
    SequenceMustHaveLength,
    Custom(String),
}

The kind of error that can be produced during a serialization or deserialization.

Variants

Io(Error)

If the error stems from the reader/writer that is being used during (de)serialization, that error will be stored and returned here.

InvalidUtf8Encoding(Utf8Error)

Returned if the deserializer attempts to deserialize a string that is not valid utf8

InvalidBoolEncoding(u8)

Returned if the deserializer attempts to deserialize a bool that was not encoded as either a 1 or a 0

InvalidCharEncoding

Returned if the deserializer attempts to deserialize a char that is not in the correct format.

InvalidTagEncoding(usize)

Returned if the deserializer attempts to deserialize the tag of an enum that is not in the expected ranges

DeserializeAnyNotSupported

Serde has a deserialize_any method that lets the format hint to the object which route to take in deserializing.

SizeLimit

If (de)serializing a message takes more than the provided size limit, this error is returned.

SequenceMustHaveLength

Bincode can not encode sequences of unknown length (like iterators).

Custom(String)

A custom error message from Serde.

Trait Implementations

impl Debug for ErrorKind

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

Formats the value using the given formatter.

impl Display for ErrorKind

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

Formats the value using the given formatter.

impl Error for Box<ErrorKind>

fn custom<T>(desc: T) -> Box<ErrorKind>

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 Error for Box<ErrorKind>

fn custom<T>(msg: T) -> Box<ErrorKind>

where T: Display,

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

impl Error for ErrorKind

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 From<Error> for Box<ErrorKind>

fn from(err: Error) -> Box<ErrorKind>

Converts to this type from the input type.
