Serialize or Deserialize error

Variants

IO(Error)

Error coming from underlying io

EOF

Unexpected EOF encountered

ExpectedMarker(&'static str)

Expected a marker of one type but received something else

ExpectedValue(&'static str)

Expected a value of one type but received something else

UnexpectedValue(&'static str)

Received an unexpected value

UTF8(usize)

Failed to convert the underlying bytes to utf8, value return the offset right before the invalid utf8

Parse

Failed to parse a float value

NaN

Received a NaN

Custom(String)

Custom error from serialize/deserialize

Implementations

impl Error

Error coming from underlying io

pub fn eof() -> Self

Unexpected EOF encountered

pub fn expected_marker(expecting: &'static str) -> Self

Expected a marker of one type but received something else

pub fn expected_value(expecting: &'static str) -> Self

Expected a value of one type but received something else

pub fn unexpected_value(unexpected: &'static str) -> Self

Received an unexpected value

pub fn utf8(valid_up_to: usize) -> Self

Failed to convert the underlying bytes to utf8, value return the offset right before the invalid utf8

pub fn overflow() -> Self

Failed to parse a float value

pub fn parse() -> Self

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 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()

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

👎 Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

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 Error for Error

fn custom<T>(msg: T) -> Self where
    T: Display, 

Used when a Serialize implementation encounters any error while serializing a type.
