Trait ArrayStatistics

pub trait ArrayStatistics {
    // Required methods
    fn is_constant(&self) -> bool;
    fn as_constant(&self) -> Option<Scalar>;
}

Extension functions for arrays that provide statistics.

Required Methods

fn is_constant(&self) -> bool

Make a best effort attempt to try and figure out if the array is constant, without canonicalizing it.

fn as_constant(&self) -> Option<Scalar>

If Self::is_constant is true, return the actual constant value as a Scalar.
