Struct GeometryAabb 

pub struct GeometryAabb;

Aggregates a native geometry column’s 2D axis-aligned bounding box (AABB) as a native geoarrow.box, the spatial analogue of min/max. Also the default zone statistic for such columns (via zone_stat_default).

Trait Implementations

impl AggregateFnVTable for GeometryAabb

type Options = EmptyOptions

Options for this aggregate function.

type Partial = AabbPartial

The partial accumulator state for a single group.

fn id(&self) -> AggregateFnId

Returns the ID of the aggregate function vtable.

fn serialize(&self, _options: &Self::Options) -> VortexResult<Option<Vec<u8>>>

Serialize the options for this aggregate function.

fn deserialize( &self, _metadata: &[u8], _session: &VortexSession, ) -> VortexResult<Self::Options>

Deserialize the options of this aggregate function.

fn return_dtype( &self, _options: &Self::Options, input_dtype: &DType, ) -> Option<DType>

The return DType of the aggregate.

fn zone_stat_default(&self, input_dtype: &DType) -> Option<AggregateFnRef>

If this aggregate should be computed as a default zone statistic for input_dtype, return the bound aggregate to store. Default: not a zone-map default.

fn partial_dtype( &self, options: &Self::Options, input_dtype: &DType, ) -> Option<DType>

DType of the intermediate partial accumulator state.

fn empty_partial( &self, _options: &Self::Options, _input_dtype: &DType, ) -> VortexResult<Self::Partial>

Return the partial accumulator state for an empty group.

fn combine_partials( &self, partial: &mut Self::Partial, other: Scalar, ) -> VortexResult<()>

Combine partial scalar state into the accumulator.

fn to_scalar(&self, partial: &Self::Partial) -> VortexResult<Scalar>

Convert the partial state into a partial scalar.

fn reset(&self, partial: &mut Self::Partial)

Reset the state of the accumulator to an empty group.

fn is_saturated(&self, _partial: &Self::Partial) -> bool

Is the partial accumulator state is “saturated”, i.e. has it reached a state where the final result is fully determined.

fn accumulate( &self, partial: &mut Self::Partial, batch: &Columnar, ctx: &mut ExecutionCtx, ) -> VortexResult<()>

Accumulate a new canonical array into the accumulator state.

fn finalize(&self, partials: ArrayRef) -> VortexResult<ArrayRef>

Finalize an array of accumulator states into an array of aggregate results.

fn finalize_scalar(&self, partial: &Self::Partial) -> VortexResult<Scalar>

Finalize a scalar accumulator state into an aggregate result.

fn coerce_args( &self, options: &Self::Options, input_dtype: &DType, ) -> Result<DType, VortexError>

Coerce the input type for this aggregate function.

fn can_satisfy( &self, options: &Self::Options, requested: &AggregateFnRef, ) -> AggregateFnSatisfaction

Return whether this stored aggregate can satisfy requested.

fn try_accumulate( &self, _state: &mut Self::Partial, _batch: &ArrayRef, _ctx: &mut ExecutionCtx, ) -> Result<bool, VortexError>

Try to accumulate the raw array before decompression.

impl Clone for GeometryAabb

fn clone(&self) -> GeometryAabb

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for GeometryAabb

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

Formats the value using the given formatter.
