pub enum OwnedArrowConversionError {

Errors cause by conversions between Arrow and owned types.

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.

UnsupportedType(DataType)

This error occurs when trying to convert from an unsupported arrow type.

DuplicateIdentifiers

This error occurs when trying to convert from a record batch with duplicate identifiers (e.g. "a" and "A").

FieldParseFail(ParseError)

This error occurs when convering from a record batch name to an identifier fails. (Which may my impossible.)

InvalidTable(OwnedTableError)

This error occurs when creating an owned table fails, which should only occur when there are zero columns.

NullNotSupportedYet

This error occurs when trying to convert from an Arrow array with nulls.

UnsupportedTimestampUnit(String)

This error occurs when trying to convert from an unsupported timestamp unit.

InvalidTimezone(String)

This error occurs when trying to convert from an invalid timezone string.

Trait Implementations

impl Debug for OwnedArrowConversionError

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

Formats the value using the given formatter.

impl Display for OwnedArrowConversionError

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

Formats the value using the given formatter.

impl Error for OwnedArrowConversionError

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, 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<&'static str> for OwnedArrowConversionError

fn from(error: &'static str) -> Self

Converts to this type from the input type.

impl From<ParseError> for OwnedArrowConversionError

fn from(source: ParseError) -> Self

Converts to this type from the input type.
