limit: Option<usize>

Implementations

impl LimitedReadPlanBuilder

fn new(inner: ReadPlanBuilder, row_count: usize) -> Self

Create a new LimitedReadPlanBuilder from the existing builder and number of rows

pub(crate) fn with_offset(self, offset: Option<usize>) -> Self

Set the offset to apply to the read plan

pub(crate) fn with_limit(self, limit: Option<usize>) -> Self

Set the limit to apply to the read plan

pub(crate) fn build_limited(self) -> ReadPlanBuilder

Apply offset and limit, updating the selection on the underlying builder and returning it.
