Errors that can occur during schema operations.

Variants

InferenceFailed(String)

Schema inference failed (e.g., not enough samples, conflicting types).

Incompatible(String)

Two schemas are incompatible and cannot be merged.

RegistryError(String)

Error communicating with a schema registry.

DecodeError(String)

Error decoding raw data into Arrow records.

EvolutionRejected(String)

A proposed schema evolution was rejected by compatibility rules.

MissingConfig(String)

A required configuration key is missing.

InvalidConfig

A configuration value is invalid.

Fields

key: String

The configuration key.

message: String

What was wrong with the value.

DuplicateWildcard

Duplicate wildcard * in the column list.

WildcardWithoutInference

Wildcard * used without a connector that supports schema inference.

WildcardPrefixCollision(String)

A wildcard-prefixed column name collides with a declared column.

WildcardNoNewFields

Wildcard expanded to zero new columns (all source columns were already declared).

Arrow(ArrowError)

An Arrow error propagated from schema operations.

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

Catch-all for wrapped external errors.

Trait Implementations

impl Debug for SchemaError

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

Formats the value using the given formatter.

impl Display for SchemaError

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

Formats the value using the given formatter.

impl Error for SchemaError

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 SchemaError

fn from(source: ArrowError) -> Self

Converts to this type from the input type.

impl From<ConnectorError> for SchemaError

fn from(err: ConnectorError) -> Self

Converts to this type from the input type.

impl From<SchemaError> for ConnectorError

fn from(err: SchemaError) -> Self

Converts to this type from the input type.
