Trait polars::chunked_array::object::ChunkApplyKernel

pub trait ChunkApplyKernel<A> {
    fn apply_kernel<F>(&self, f: F) -> Self
    where
        F: Fn(&A) -> Arc<dyn Array + 'static>;
    fn apply_kernel_cast<F, S>(&self, f: F) -> ChunkedArray<S>
    where
        F: Fn(&A) -> Arc<dyn Array + 'static>,
        S: PolarsDataType;
}

Apply kernels on the arrow array chunks in a ChunkedArray.

Required methods

fn apply_kernel<F>(&self, f: F) -> Self where
    F: Fn(&A) -> Arc<dyn Array + 'static>, 

Apply kernel and return result as a new ChunkedArray.

fn apply_kernel_cast<F, S>(&self, f: F) -> ChunkedArray<S> where
    F: Fn(&A) -> Arc<dyn Array + 'static>,
    S: PolarsDataType, 

Apply a kernel that outputs an array of different type.
