Struct Error 

pub struct Error { /* private fields */ }

Error when a Serializer or Deserializer trait object fails.

Trait Implementations

impl Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

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

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) -> Error

where T: Display,

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

impl Error for Error

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

where T: Display,

Raised when there is general error when deserializing a type.

fn invalid_type(unexpected: Unexpected<'_>, expected: &dyn Expected) -> Error

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

fn invalid_value(unexpected: Unexpected<'_>, expected: &dyn Expected) -> Error

Raised when a Deserialize receives a value of the right type but that is wrong for some other reason.

fn invalid_length(len: usize, expected: &dyn Expected) -> Error

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]) -> Error

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

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

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

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

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) -> Error

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