Error when (de-)serializing.

Variants

UnexpectedEnd

Expected more data but encountered the end of the input.

ExcessData

Excess data appeared at the end of the input.

BufferTooSmall

Buffer was too small.

Allocation

Allocation failure.

UsizeOverflow

Usize overflow.

LimitReached

Configured size limit reached.

InvalidType(u8)

Invalid data type designator encountered.

VarIntTooLarge

VarInt too large for the given expected type.

WrongType(Type, &'static [Type])

Wrong data type encountered (found, expected).

NotOneChar

String is not exactly one character.

Format(Error)

Formatting error. Happens serializing a core::fmt::Display value and could be due to an output writing failure.

StringNotUtf8(Utf8Error)

Parsed string is not valid UTF-8.

Io(Error)

IO error.

Custom

no-std + no-alloc: Generic error message that can be created by data structures through the ser::Error and de::Error traits.

Message(String)

alloc: Generic error message that can be created by data structures through the ser::Error and de::Error traits.

Trait Implementations

impl Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

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

Formats the value using the given formatter.

impl Error for Error

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 Error

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

where T: Display,

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

impl Error for Error

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.

impl From<Error> for Error

fn from(err: Error) -> Self

Converts to this type from the input type.

impl From<Error> for Error

fn from(err: Error) -> Self

Converts to this type from the input type.

impl From<Utf8Error> for Error

fn from(err: Utf8Error) -> Self

Converts to this type from the input type.
