Trait GreatestLeastOperator 

pub(super) trait GreatestLeastOperator {
    const NAME: &'static str;

    // Required methods
    fn keep_scalar<'a>(
        lhs: &'a ScalarValue,
        rhs: &'a ScalarValue,
    ) -> Result<&'a ScalarValue>;
    fn get_indexes_to_keep(
        lhs: &dyn Array,
        rhs: &dyn Array,
    ) -> Result<BooleanArray>;
}

Required Associated Constants

const NAME: &'static str

Required Methods

fn keep_scalar<'a>( lhs: &'a ScalarValue, rhs: &'a ScalarValue, ) -> Result<&'a ScalarValue>

fn get_indexes_to_keep(lhs: &dyn Array, rhs: &dyn Array) -> Result<BooleanArray>

Return array with true for values that we should keep from the lhs array

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
