Struct DecodedColumnStats 

#[non_exhaustive]
pub struct DecodedColumnStats { /* private fields */ }

Typed adapter view of the supported sketches for one column.

Implementations

impl DecodedColumnStats

pub const fn field_id(&self) -> i32

pub const fn column_stats(&self) -> &ColumnStats

Canonical scalar statistics suitable for native planner adapters.

The HLL contributes distinct_count. A histogram remains available through Self::histogram but does not imply a full table row count.

pub const fn hll(&self) -> Option<&HllSketch>

pub const fn histogram(&self) -> Option<&EquiDepthHistogram>
