Struct RepDefSlicer

pub struct RepDefSlicer<'a> { /* private fields */ }

Slices a level buffer into pieces

This is needed to handle the fact that a level buffer may have more levels than values due to special (empty/null) lists.

As a result, a call to slice_next(10) may return 10 levels or it may return more than 10 levels if any special values are encountered.

Implementations

impl<'a> RepDefSlicer<'a>

pub fn num_levels(&self) -> usize

pub fn num_levels_remaining(&self) -> usize

pub fn all_levels(&self) -> &LanceBuffer

pub fn slice_rest(&mut self) -> LanceBuffer

Returns the rest of the levels not yet sliced

This must be called instead of slice_next on the final iteration. This is because anytime we slice there may be empty/null lists on the boundary that are “free” and the current behavior in slice_next is to leave them for the next call.

slice_rest will slice all remaining levels and return them.

pub fn slice_next(&mut self, num_values: usize) -> LanceBuffer

Returns enough levels to satisfy the next num_values values
