Enum nu_json::error::Error

pub enum Error {
    Syntax(ErrorCode, usize, usize),
    Io(Error),
    FromUtf8(FromUtf8Error),
}

This type represents all possible errors that can occur when serializing or deserializing a value into JSON.

Variants

Syntax(ErrorCode, usize, usize)

The JSON value had some syntactic error.

Tuple Fields of Syntax

0: ErrorCode1: usize2: usize

Io(Error)

Some IO error occurred when serializing or deserializing a value.

Tuple Fields of Io

0: Error

FromUtf8(FromUtf8Error)

Some UTF8 error occurred while serializing or deserializing a value.

Tuple Fields of FromUtf8

0: FromUtf8Error

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, fmt: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Error for Error

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

👎 Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

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

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

fn backtrace(&self) -> Option<&Backtrace>

🔬 This is a nightly-only experimental API. (backtrace)

Returns a stack backtrace, if available, of where this error occurred.

fn description(&self) -> &str

👎 Deprecated since 1.42.0:

use the Display impl or to_string()

impl Error for Error

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

Raised when there is general error when deserializing a type.

impl Error for Error

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

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<Error> for Error

fn from(error: Error) -> Error

Performs the conversion.

impl From<FromUtf8Error> for Error

fn from(error: FromUtf8Error) -> Error

Performs the conversion.
