Trait Implementations

impl Debug for DecodeError

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

Formats the value using the given formatter.

impl Display for DecodeError

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

Formats the value using the given formatter.

impl Error for DecodeError

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 description(&self) -> &str

👎Deprecated since 1.42.0: use the Display impl or to_string()

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 DecodeError

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

Raised when there is general error when deserializing a type.

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

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

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

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) -> DecodeError

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], ) -> DecodeError

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

fn unknown_field(field: &str, _expected: &'static [&'static str]) -> DecodeError

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

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

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) -> DecodeError

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

impl From<Error> for DecodeError

fn from(err: Error) -> DecodeError

Converts to this type from the input type.

impl From<FromUtf8Error> for DecodeError

fn from(err: FromUtf8Error) -> DecodeError

Converts to this type from the input type.
