Errors that can occur during WPL-to-Arrow type conversion.

Variants

UnsupportedDataType(String)

The given type name is not a recognized WPL data type.

InvalidArrayInnerType(String)

An array<...> type has an invalid or missing inner type.

EmptyFieldName

A field definition has an empty name.

MissingRequiredField

A required (non-nullable) field is missing from the record.

Fields

field_name: String

ArrowBuildError(String)

Wrapper for arrow::error::ArrowError (stored as String because ArrowError is not Clone/Eq).

ValueConversionError

A field value does not match the expected WpDataType.

Fields

field_name: String

expected: String

actual: String

SchemaMismatch

The number of FieldDefs does not match the number of columns in the RecordBatch.

Fields

expected: usize

actual: usize

TimestampOverflow

A NaiveDateTime value overflows the i64 nanosecond representation.

Fields

field_name: String

ParseError

Failed to parse a string value back into the expected type.

Fields

field_name: String

detail: String

IpcEncodeError(String)

IPC encoding failed (wraps Arrow IPC writer errors).

IpcDecodeError(String)

IPC decoding failed (malformed frame, incomplete data, etc.).

Trait Implementations

impl Clone for WpArrowError

fn clone(&self) -> WpArrowError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for WpArrowError

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

Formats the value using the given formatter.

impl Display for WpArrowError

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

Formats the value using the given formatter.

impl Eq for WpArrowError

impl Error for WpArrowError

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 PartialEq for WpArrowError

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

Equality operator ==.

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

Inequality operator !=.
