Trait Implementations

impl Clone for DeserializeError

fn clone(&self) -> DeserializeError

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for DeserializeError

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

Formats the value using the given formatter.

impl Display for DeserializeError

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

Formats the value using the given formatter.

impl Error for DeserializeError

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 DeserializeError

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

where T: Display,

Raised when there is general error when deserializing a type.

fn unknown_field( field: &str, expected: &'static [&'static str], ) -> DeserializeError

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

fn unknown_variant( variant: &str, expected: &'static [&'static str], ) -> DeserializeError

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

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

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) -> DeserializeError

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

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.

impl From<DeserializeError> for Error

fn from(source: DeserializeError) -> Error

Converts to this type from the input type.

impl From<DeserializeError> for Error

fn from(source: DeserializeError) -> Self

Converts to this type from the input type.

impl IntoDeserializer<'_, DeserializeError> for Object

type Deserializer = Deserializer

The type of the deserializer being converted into.

fn into_deserializer(self) -> Deserializer

Convert this value into a deserializer.

impl PartialEq for DeserializeError

fn eq(&self, other: &DeserializeError) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
