This type represents all possible errors that can occur when deserializing JSON data

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.

EofWhileParsingList

EOF while parsing a list.

EofWhileParsingObject

EOF while parsing an object.

EofWhileParsingString

EOF while parsing a string.

EofWhileParsingNumber

EOF while parsing a JSON number.

EofWhileParsingValue

EOF while parsing a JSON value.

ExpectedColon

Expected this character to be a ':'.

ExpectedListCommaOrEnd

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

ExpectedObjectCommaOrEnd

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

ExpectedSomeIdent

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

ExpectedSomeValue

Expected this character to start a JSON value.

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.

TrailingComma

JSON has a comma after the last value in an array or map.

CustomError

Error with a custom message that we had to discard.

InvalidEscape

Invalid escape

ControlCharacterWhileParsingString

Control character while parsing string

CustomErrorWithMessage(String)

Error with a custom message that was preserved.

Trait Implementations

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>(msg: T) -> Self

where T: Display,

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 PartialEq for Error

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