Enum Error

pub enum Error {
    UnexpectedEndOfInput,
    InvalidChar,
    InvalidUtf8,
    DataBeyondEnd,
    ValueOverflow,
    UnexpectedWireType,
    InvalidMap,

}

Variants

UnexpectedEndOfInput

The input was incomplete.

InvalidChar

The value read was not a valid char.

InvalidUtf8

The byte array read did not contain valid UTF-8.

DataBeyondEnd

The input was longer than expected. If it was expected, please use from_bytes_more_data.

ValueOverflow

The value read doesn’t fit into the expected integer type.

UnexpectedWireType

The wire type of the value doesn’t match the expected type

InvalidMap

A sequence with an odd number of elements was read, which is invalid for a map.

Serialization(String)

Serde framework error.

Deserialization(String)

Serde framework error.

IO(Error)

I/O error in writer.

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, __formatter: &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: Display>(msg: T) -> Self

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

impl Error for Error

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

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<CharTryFromError> for Error

fn from(_e: CharTryFromError) -> Self

Converts to this type from the input type.

impl From<Error> for Error

fn from(e: Error) -> Self

Converts to this type from the input type.

impl From<TryFromIntError> for Error

fn from(_e: TryFromIntError) -> Self

Converts to this type from the input type.

impl From<Utf8Error> for Error

fn from(_e: Utf8Error) -> Self

Converts to this type from the input type.
