A decoding error.

Variants

Msg(String)

Custom error message.

Read(E)

IO error.

Eof

End of file.

Mismatch

Unexpected byte.

Fields

expect_major: u8

Expected CBOR major type.

byte: u8

Unexpected byte.

TypeMismatch

Unexpected type.

Fields

name: &'static str

Type name.

byte: u8

Type byte.

CastOverflow(TryFromIntError)

Too large integer.

Overflow

Overflowing 128-bit integers.

Fields

name: &'static str

Type of integer.

RequireBorrowed

Decoding bytes/strings might require a borrow.

Fields

name: &'static str

Type name (e.g. “bytes”, “str”).

RequireLength

Length wasn’t large enough.

Fields

name: &'static str

Type name.

expect: usize

Required length.

value: usize

Given length.

InvalidUtf8(Utf8Error)

Invalid UTF-8.

Unsupported

IndefiniteSize

Indefinite sized item was encountered.

Trait Implementations

impl<E: Debug> Debug for DecodeError<E>

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

Formats the value using the given formatter.

impl<E: Debug> Display for DecodeError<E>

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

Formats the value using the given formatter.

impl<E: Debug> Error for DecodeError<E>

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

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<E: Debug> Error for DecodeError<E>

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

Returns 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<E: Debug> From<DecodeError<E>> for DecodeError<E>

fn from(err: DecodeError<E>) -> DecodeError<E>

Converts to this type from the input type.

impl From<DecodeError<Infallible>> for CodecError

fn from(error: DecodeError<Infallible>) -> Self

Converts to this type from the input type.

impl<E> From<E> for DecodeError<E>

fn from(err: E) -> DecodeError<E>

Converts to this type from the input type.
