DataFusion error

Variants

ArrowError(ArrowError)

Error returned by arrow.

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.

SchemaError(SchemaError)

This error happens with schema-related errors, such as 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.

ResourcesExhausted(String)

This error is thrown when a consumer cannot acquire memory from the Memory Manager we can just cancel the execution of the partition.

External(Box<dyn Error + Send + Sync>)

Errors originating from outside DataFusion’s core codebase. For example, a custom S3Error from the crate datafusion-objectstore-s3

Context(String, Box<DataFusionError>)

Error with additional context

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

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 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.
