Trait SumMeanHorizontal 

pub trait SumMeanHorizontal {
    // Required methods
    fn sum_horizontal(
        &self,
        null_strategy: NullStrategy,
    ) -> PolarsResult<Option<Column>>;
    fn mean_horizontal(
        &self,
        null_strategy: NullStrategy,
    ) -> PolarsResult<Option<Column>>;
}

Required Methods

fn sum_horizontal( &self, null_strategy: NullStrategy, ) -> PolarsResult<Option<Column>>

Sum all values horizontally across columns.

fn mean_horizontal( &self, null_strategy: NullStrategy, ) -> PolarsResult<Option<Column>>

Compute the mean of all numeric values horizontally across columns.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
