Struct serde_cbor::error::Error

pub struct Error(_);

This type represents all possible errors that can occur when serializing or deserializing CBOR data.

Methods

impl Error

pub fn offset(&self) -> u64

The byte offset at which the error occurred.

pub fn classify(&self) -> Category

Categorizes the cause of this error.

pub fn is_io(&self) -> bool

Returns true if this error was caused by a failure to read or write bytes on an IO stream.

pub fn is_syntax(&self) -> bool

Returns true if this error was caused by input that was not syntactically valid CBOR.

pub fn is_data(&self) -> bool

Returns true if this error was caused by data that was semantically incorrect.

pub fn is_eof(&self) -> bool

Returns true if this error was caused by prematurely reaching the end of the input data.

Trait Implementations

impl Error for Error

fn description(&self) -> &str

A short description of the error.

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

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

impl Display for Error

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

Formats the value using the given formatter.

impl Debug for Error

fn fmt(&self, fmt: &mut Formatter) -> Result

Formats the value using the given formatter.

impl Error for Error

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

Raised when there is general error when deserializing a type.

fn invalid_type(unexp: Unexpected, exp: &Expected) -> Error

Raised when a Deserialize receives a type different from what it was expecting.

fn invalid_value(unexp: Unexpected, exp: &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: &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) -> Error where
    T: Display, 

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