Deserialization error

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

UnexpectedEof

EOF while parsing

InvalidEscapeSequence

Invalid JSON string escape sequence

StringControlChar

A control ASCII character detected in a JSON input

ExpectedColon

Expected this character to be a ':'.

ExpectedArrayCommaOrEnd

Expected this character to be either a ',' or a ']'.

LeadingArrayComma

Array content starts with a leading ,.

TrailingArrayComma

Array content ends with a trailing ,.

ExpectedObjectCommaOrEnd

Expected this character to be either a ',' or a '}'.

LeadingObjectComma

Object content starts with a leading ,.

TrailingObjectComma

Object content ends with a trailing ,.

ExpectedToken

Expected to parse either a true, false, or a null.

ExpectedNull

Expected null

ExpectedString

Expected " character

ExpectedArrayEnd

Expected ‘]’

ExpectedArray

Expected array

ExpectedObject

Expected object

ExpectedStruct

Expected object or array

ExpectedEnumValue

Expected this character to start an enum variant.

ExpectedEnumObjectEnd

Expected this character to be '}'.

InvalidNumber

Invalid number

InvalidType

Invalid type

InvalidUnicodeCodePoint

Invalid unicode code point

KeyMustBeAString

Object key is not a string

TrailingCharacters

JSON has non-whitespace trailing characters after the value

UnexpectedChar

Unexpected character

InvalidLength

Invalid length

DeserializeError(String)

Available on crate features std or alloc only.

An error passed down from a serde::de::Deserialize implementation

Trait Implementations

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 Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

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

Formats the value using the given formatter.

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<ParseFloatError> for Error

fn from(_err: ParseFloatError) -> Self

Converts to this type from the input type.

impl From<ParseIntError> for Error

fn from(_err: ParseIntError) -> Self

Converts to this type from the input type.

impl From<Utf8Error> for Error

fn from(_err: Utf8Error) -> Self

Converts to this type from the input type.

impl PartialEq 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: &Rhs) -> bool

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

impl Error for Error

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

The underlying cause of this error, if any.

impl Eq for Error

impl StructuralPartialEq for Error
