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; }
Expand description

Apply kernels on the arrow array chunks in a ChunkedArray.

Required Methods§

source

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

Apply kernel and return result as a new ChunkedArray.

source

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.
