Expand description

Apply kernels on the arrow array chunks in a ChunkedArray.

Required Methods§

source

fn apply_kernel(&self, f: &dyn Fn(&A) -> ArrayRef) -> Self

Apply kernel and return result as a new ChunkedArray.

source

fn apply_kernel_cast<S>(&self, f: &dyn Fn(&A) -> ArrayRef) -> ChunkedArray<S>where S: PolarsDataType,

Apply a kernel that outputs an array of different type.
