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

Variants

IoError

Fields

source: Error

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

Incomplete

Fields

label: &'static str

position: Position

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.

EncodingError

Fields

description: String

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

DecodingError

Fields

description: String

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

IllegalOperation

Fields

operation: String

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

Trait Implementations

impl Clone for IonError

fn clone(&self) -> Self

Returns a copy 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)>

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 From<Error> for IonError

fn from(error: Error) -> Self

Converts to this type from the input type.

impl From<Error> for IonError

fn from(source: Error) -> Self

Converts to this type from the input type.

impl PartialEq<IonError> for IonError

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.
