Trait polars::prelude::ChunkApplyKernel

pub trait ChunkApplyKernel<A>
where
    A: Array,
{
    // Required methods
    fn apply_kernel(&self, f: &dyn Fn(&A) -> Box<dyn Array>) -> Self;
    fn apply_kernel_cast<S>(
        &self,
        f: &dyn Fn(&A) -> Box<dyn Array>
    ) -> ChunkedArray<S>
       where S: PolarsDataType;
}

Apply kernels on the arrow array chunks in a ChunkedArray.

Required Methods

fn apply_kernel(&self, f: &dyn Fn(&A) -> Box<dyn Array>) -> Self

Apply kernel and return result as a new ChunkedArray.

fn apply_kernel_cast<S>( &self, f: &dyn Fn(&A) -> Box<dyn Array> ) -> ChunkedArray<S>

where S: PolarsDataType,

Apply a kernel that outputs an array of different type.
