Struct SelectorsCursor 

pub struct SelectorsCursor {
    selectors: VecDeque<RowSelector>,
    position: usize,
}

Cursor for iterating a selector-backed RowSelection

This is best for sparse selections where large contiguous blocks of rows are selected or skipped.

Fields

selectors: VecDeque<RowSelector>

position: usize

Current absolute offset into the selection

Implementations

impl SelectorsCursor

pub fn is_empty(&self) -> bool

Returns true when no further rows remain

pub(crate) fn selectors_mut(&mut self) -> &mut VecDeque<RowSelector>

pub(crate) fn next_selector(&mut self) -> RowSelector

Return the next RowSelector

pub(crate) fn return_selector(&mut self, selector: RowSelector)

Return a selector to the front, rewinding the position
