Enum IonError 

#[non_exhaustive]
pub enum IonError {
    Io(IoError),
    Incomplete(IncompleteError),
    Encoding(EncodingError),
    Decoding(DecodingError),
    IllegalOperation(IllegalOperation),
    Conversion(ConversionError),
}

Represents the different types of high-level failures that might occur when reading Ion data.

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.

Io(IoError)

Indicates that an IO error was encountered while reading or writing.

Incomplete(IncompleteError)

Indicates that the input buffer did not contain enough data to perform the requested read operation. If the input source contains more data, the reader can append it to the buffer and try again.

Encoding(EncodingError)

Indicates that the writer encountered a problem while serializing a given piece of data.

Decoding(DecodingError)

Indicates that the data stream being read contained illegal or otherwise unreadable data.

IllegalOperation(IllegalOperation)

Returned when the user has performed an illegal operation (for example: calling stepOut() on the cursor at the top level.)

Conversion(ConversionError)

Returned when the user has attempted to convert a value to a type for which that value is not trivially convertable.

Trait Implementations

impl Clone for IonError

fn clone(&self) -> IonError

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for IonError

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

Formats the value using the given formatter.

impl Display for IonError

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

Formats the value using the given formatter.

impl Error for IonError

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<FromType, ToType> From<ConversionOperationError<FromType, ToType>> for IonError

where FromType: ValueTypeExpectation, ToType: TypeExpectation,

fn from(err: ConversionOperationError<FromType, ToType>) -> Self

Converts to this type from the input type.

impl From<Error> for IonError

fn from(io_error: Error) -> Self

Converts to this type from the input type.

impl From<Error> for IonError

fn from(error: Error) -> Self

Converts to this type from the input type.

impl From<ErrorKind> for IonError

fn from(error_kind: ErrorKind) -> Self

Converts to this type from the input type.

impl From<IonError> for Error

fn from(_ion_error: IonError) -> Self

Converts to this type from the input type.

impl PartialEq for IonError

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