DataFusion error

Variants

ArrowError(ArrowError)

Error returned by arrow.

ParquetError(ParquetError)

Wraps an error from the Parquet crate

IoError(Error)

Error associated to I/O operations and associated traits.

SQL(ParserError)

Error returned when SQL is syntactically incorrect.

NotImplemented(String)

Error returned on a branch that we know it is possible but to which we still have no implementation for. Often, these errors are tracked in our issue tracker.

Internal(String)

Error returned as a consequence of an error in DataFusion. This error should not happen in normal usage of DataFusion.

Plan(String)

This error happens whenever a plan is not valid. Examples include impossible casts, schema inference not possible and non-unique column names.

Execution(String)

Error returned during execution of the query. Examples include files not found, errors in parsing certain types.

Implementations

impl DataFusionError

pub fn into_arrow_external_error(self) -> ArrowError

Wraps this DataFusionError as an arrow::error::ArrowError.

Trait Implementations

impl Debug for DataFusionError

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

Formats the value using the given formatter.

impl Display for DataFusionError

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

Formats the value using the given formatter.

impl Error for DataFusionError

pub fn source(&self) -> Option<&(dyn Error + 'static)>

The lower-level source of this error, if any.

pub fn backtrace(&self) -> Option<&Backtrace>

🔬 This is a nightly-only experimental API. (backtrace)

Returns a stack backtrace, if available, of where this error occurred.

pub fn description(&self) -> &str

👎 Deprecated since 1.42.0:

use the Display impl or to_string()

pub fn cause(&self) -> Option<&dyn Error>

👎 Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting
