Enum serde::de::value::Error

pub enum Error {
    Custom(String),
    InvalidType(Type),
    InvalidLength(usize),
    InvalidValue(String),
    EndOfStream,
    UnknownVariant(String),
    UnknownField(String),
    MissingField(&'static str),
}

This represents all the possible errors that can occur using the ValueDeserializer.

Variants

Custom(String)

The value had some custom error.

InvalidType(Type)

The value had an incorrect type.

InvalidLength(usize)

The value had an invalid length.

InvalidValue(String)

The value is invalid and cannot be deserialized.

EndOfStream

EOF while deserializing a value.

UnknownVariant(String)

Unknown variant in enum.

UnknownField(String)

Unknown field in struct.

MissingField(&'static str)

Struct is missing a field.

Trait Implementations

impl Error for Error

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

Raised when there is general error when deserializing a type.

fn end_of_stream() -> Self

Raised when a Deserialize type unexpectedly hit the end of the stream.

fn invalid_type(ty: Type) -> Self

Raised when a Deserialize was passed an incorrect type.

fn invalid_value(msg: &str) -> Self

Raised when a Deserialize was passed an incorrect value.

fn invalid_length(len: usize) -> Self

Raised when a fixed sized sequence or map was passed in the wrong amount of arguments.

fn unknown_variant(variant: &str) -> Self

Raised when a Deserialize enum type received an unexpected variant.

fn unknown_field(field: &str) -> Self

Raised when a Deserialize struct type received an unexpected struct field.

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

raised when a deserialize struct type did not receive a field.

fn duplicate_field(field: &'static str) -> Self

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

impl Clone for Error

fn clone(&self) -> Error

Returns a copy of the value.

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

Performs copy-assignment from source.

impl PartialEq<Error> for Error

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

This method tests for self and other values to be equal, and is used by ==.

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

This method tests for !=.

impl Display for Error

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

Formats the value using the given formatter.

impl Debug for Error

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

Formats the value using the given formatter.

impl Error for Error

fn description(&self) -> &str

This method is soft-deprecated.

fn cause(&self) -> Option<&dyn Error>

Deprecating in 1.33.0

: replaced by Error::source, which can support downcasting

The lower-level cause of this error, if any.

fn source(&self) -> Option<&(dyn Error + 'static)>

The lower-level source of this error, if any.
