Error types that can occur during ElastiCube operations

This enum is marked as #[non_exhaustive] to allow adding new error variants in future versions without breaking changes. When pattern matching, always include a catch-all arm (_) to handle future variants.

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.

Arrow(ArrowError)

Arrow-related errors

DataFusion(DataFusionError)

DataFusion-related errors

Io(Error)

IO errors

Schema(String)

Schema validation errors

Dimension(String)

Dimension-related errors

Measure(String)

Measure-related errors

Hierarchy(String)

Hierarchy-related errors

Query(String)

Query-related errors

DataSource(String)

Data source errors

TypeConversion(String)

Type conversion errors

Config(String)

Invalid configuration

Builder(String)

Builder-related errors

Data(String)

Data loading errors

Other(String)

Generic error with custom message

Trait Implementations

impl Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

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

Formats the value using the given formatter.

impl Error for Error

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 From<ArrowError> for Error

fn from(source: ArrowError) -> Self

Converts to this type from the input type.

impl From<DataFusionError> for Error

fn from(source: DataFusionError) -> Self

Converts to this type from the input type.

impl From<Error> for Error

fn from(source: Error) -> Self

Converts to this type from the input type.
