An error encountered while decoding CBOR.

Variants

Underrun

Early end of data.

UnsupportedHeaderValue(u8)

Unsupported value in CBOR header.

NonCanonicalInt

An integer was encoded in non-canonical form.

NonCanonicalFloat

A floating point value was encoded in non-canonical form.

InvalidString(Utf8Error)

An invalidly-encoded UTF-8 string was encountered.

UnusedData(usize)

The decoded CBOR had extra data at the end.

MisorderedMapKey

The decoded CBOR map has keys that are not in canonical order.

DuplicateMapKey

The decoded CBOR map has a duplicate key.

IntegerOutOfRange

The decoded integer could not be represented in the specified integer type.

WrongType

The decoded value was not the expected type.

WrongTag(Tag, Tag)

The decoded value did not have the expected tag.

The case includes the expected tag and encountered tag as associated data.

InvalidFormat

Invalid CBOR format. Frequently thrown by libraries depending on this one.

Trait Implementations

impl Debug for DecodeError

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

Formats the value using the given formatter.

impl Display for DecodeError

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

Formats the value using the given formatter.

impl Error for DecodeError

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, demand: &mut Demand<'a>)

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

Provides type based access to context intended for error reports.

impl PartialEq<DecodeError> for DecodeError

fn eq(&self, other: &Self) -> 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.
