Enum Error 

#[non_exhaustive]
pub enum Error {
    IncompatibleType,
    Overflow,
    NegativeUnsigned,
    Precision,
    InvalidSimpleValue,
    InvalidEncoding,
    InvalidUtf8,
    UnexpectedEof,
    LengthTooLarge,
    Io(Error),
}

Errors produced during CBOR encoding, decoding, or value access.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

IncompatibleType

Accessor called on a value of the wrong CBOR type.

Overflow

Integer does not fit in the target type.

NegativeUnsigned

Attempted to read a negative integer as an unsigned type.

Precision

Float conversion would lose precision.

InvalidSimpleValue

Simple value number is in the reserved range 24-31.

InvalidEncoding

CBOR input is not in canonical (deterministic) form.

InvalidUtf8

Text string contains invalid UTF-8.

UnexpectedEof

Input ended before a complete data item was read.

LengthTooLarge

Declared length exceeds addressable memory.

Io(Error)

Underlying I/O error.

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)>

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 From<Error> for Error

fn from(err: Error) -> Self

Converts to this type from the input type.

impl From<Error> for Error

fn from(err: Error) -> Self

Converts to this type from the input type.

impl PartialEq for Error

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

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
