An error from parsing JSON.

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.

Utf8

An invalid UTF-8 sequence was encountered.

UnexpectedEof

An end-of-file was encountered when it wasn’t expected.

ExpectedObjectKey

While parsing an object, something was encountered that was not a valid object key.

ExpectedColon

While parsing an object, a colon was expected after an object’s key.

ExpectedValue

A Value was expected.

ExpectedCommaOrEndOfObject

While parsing an object, either the end of an object (}) or a comma was expected.

ExpectedCommaOrEndOfArray

While parsing an array, either the end of an array (]) or a comma was expected.

IllegalTrailingComma

When parsing an object or an array, a trailing comma was detected. The JSON specification disallows trailing commas.

Unexpected(u8)

An unexpected character was encountered while parsing a Value.

TrailingNonWhitespace

The source being parsed contained additional non-whitespace data after a Value was parsed.

ObjectKeysMustBeStrings

A non-string was encountered for an object key. The JSON standard requires all keys to be strings.

ExpectedExponent

An exponent was expected on a floating point number.

ExpectedDecimalDigit

At least one decimal digit was expected on a floating point number.

ExpectedDigit

At least one integer digit was expected on a floating point number.

InvalidHexadecimal

An invalid hexadecimal character was encountered in a unicode escape sequence in a string.

InvalidEscape

An invalid character was escaped.

UnclosedObject

An object is missing its end (}).

UnclosedArray

An array is missing its end (]).

UnclosedString

A string is missing its end (").

ExpectedString

A string was expected, but another type was found.

ExpectedNumber

A number was expected, but another type was found.

RecursionLimitReached

The JSON being parsed has more depth than the parser was configured to allow.

PayloadsShouldBeObjectOrArray

A value that wasn’t an object or array was contained in a JSON payload.

This error is only returned when the allow_all_types_at_root configuration is set to false.

PaylodTooLarge

A GenericDocument being parsed was too large to fit in the collection provided.

ErrorFromDelegate(DelegateError)

An error was returned from a ParseDelegate.

Trait Implementations

impl<DelegateError: Clone> Clone for ErrorKind<DelegateError>

fn clone(&self) -> ErrorKind<DelegateError>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<DelegateError: Debug> Debug for ErrorKind<DelegateError>

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

Formats the value using the given formatter.

impl<DelegateError> Display for ErrorKind<DelegateError>

where DelegateError: Display,

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

Formats the value using the given formatter.

impl<DelegateError> Error for ErrorKind<DelegateError>

where DelegateError: Debug + Display,

Available on crate feature std only.

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

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<DelegateError: PartialEq> PartialEq for ErrorKind<DelegateError>

fn eq(&self, other: &ErrorKind<DelegateError>) -> 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.
