Trait ChunkZip 

pub trait ChunkZip<T>
where
    T: PolarsDataType,
{
    // Required method
    fn zip_with(
        &self,
        mask: &ChunkedArray<BooleanType>,
        other: &ChunkedArray<T>,
    ) -> Result<ChunkedArray<T>, PolarsError>;
}

Combine two ChunkedArray based on some predicate.

Required Methods

fn zip_with( &self, mask: &ChunkedArray<BooleanType>, other: &ChunkedArray<T>, ) -> Result<ChunkedArray<T>, PolarsError>

Create a new ChunkedArray with values from self where the mask evaluates true and values from other where the mask evaluates false

Dyn Compatibility

This trait is dyn compatible.

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