Fields

null_count: Box<dyn Array>

number of nulls. This is a UInt64Array for non-nested types

min_value: Box<dyn Array>

Minimum

max_value: Box<dyn Array>

Maximum

Trait Implementations

impl Debug for Statistics

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

Formats the value using the given formatter.

impl PartialEq for Statistics

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

This method tests for self and other values to be equal, and is used by ==.

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

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