Struct GenericInProgressArray 

pub(crate) struct GenericInProgressArray {
    source: Option<ArrayRef>,
    buffered_arrays: Vec<ArrayRef>,
}

Generic implementation for InProgressArray that works with any type of array.

Internally, this buffers arrays and then calls other kernels such as concat to produce the final array.

Fields

source: Option<ArrayRef>

The current source

buffered_arrays: Vec<ArrayRef>

The buffered array slices

Implementations

impl GenericInProgressArray

pub(crate) fn new() -> Self

Create a new GenericInProgressArray

fn copy_rows(&mut self, offset: usize, len: usize) -> Result<(), ArrowError>
