Failure to construct the ABI-v1 typed-key encoder.

Variants

EmptyKeySchema

A keyed partitioning codec requires at least one logical key column.

TooManyKeyColumns

The composite key is too wide for bounded plan-time construction.

Fields

count: usize

Requested key-column count.

limit: usize

Hard key-column limit.

UnsupportedKeyMetadata

Arrow extension metadata has no routing semantics in partitioning ABI v1.

Fields

index: usize

Zero-based position in the composite key.

KeyTypeNestingTooDeep

Recursive dictionary hydration is bounded before Arrow row construction.

Fields

index: usize

Zero-based position in the composite key.

limit: usize

Hard dictionary nesting limit.

KeyTypeParameterTooLarge

A variable type parameter crossed its partition ABI resource bound.

Fields

index: usize

Zero-based position in the composite key.

parameter: &'static str

Bounded type parameter.

bytes: usize

Observed parameter bytes.

limit: usize

Hard parameter limit.

UnsupportedKeyType

The resolved key type has no frozen ABI-v1 equality and encoding contract.

Fields

index: usize

Zero-based position in the composite key.

data_type: DataType

Rejected Arrow type.

UnsupportedKeyTypeFamily

A recursive Arrow family is rejected without cloning attacker-shaped schema trees.

Fields

index: usize

Zero-based position in the composite key.

family: &'static str

Stable rejected family label.

Arrow(ArrowError)

Arrow rejected the otherwise admitted row layout.

KeySchemaDescriptorTooLarge

The opaque routing-schema descriptor crossed its hard allocation bound.

Fields

limit: usize

Hard encoded descriptor limit.

Trait Implementations

impl Debug for PartitionKeyCodecError

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

Formats the value using the given formatter.

impl Display for PartitionKeyCodecError

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

Formats the value using the given formatter.

impl Error for PartitionKeyCodecError

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 PartitionKeyCodecError

fn from(source: ArrowError) -> Self

Converts to this type from the input type.
