Struct GeoStatistics 

pub struct GeoStatistics { /* private fields */ }

Statistics specific to spatial data types

These statistics are an abstraction to provide sedonadb the ability to perform generic pruning and optimization for datasources that have the ability to provide this information. This may evolve to support more fields; however, can currently express Parquet built-in GeoStatistics, GeoParquet metadata, and GDAL OGR (via GetExtent() and GetGeomType()). This struct can also represent partial or missing information.

Implementations

pub fn merge(&mut self, other: &Self)

Update this statistics object with another one

pub fn try_from_column_statistics( stats: &ColumnStatistics, ) -> Result<Option<Self>>

Try to deserialize GeoStatistics from DataFusion ColumnStatistics

Various DataFusion APIs operate on ColumnStatistics, which do not support spatial statistics natively. This function attempts to reconstruct an object that was canonically serialized into one of these objects for transport through DataFusion internals.

pub fn to_column_statistics(&self) -> Result<ColumnStatistics>

Serialize this object into a ColumnStatistics

Canonically place this object into a ColumnStatistics for transport through DataFusion APIs.

pub fn try_with_str_geometry_types( self, geometry_types: Option<&[&str]>, ) -> Result<Self>

Add a definitive list of geometry type/dimension values specified as strings

This accepts a list of strings like “point z” or “polygon zm”. These strings are case insensitive.

pub fn to_scalar_value(&self) -> Result<ScalarValue>

Convert this GeoStatistics to a ScalarValue for storage in DataFusion statistics

Trait Implementations

impl Clone for GeoStatistics

fn clone(&self) -> GeoStatistics

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for GeoStatistics

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for GeoStatistics

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl From<GeoStatistics> for TableGeoStatistics

fn from(value: GeoStatistics) -> Self

Converts to this type from the input type.

impl PartialEq for GeoStatistics

fn eq(&self, other: &GeoStatistics) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
