Struct AliveSet 

pub struct AliveSet { /* private fields */ }

Disjoint per-segment alive and tombstone bitmaps.

Implementations

impl AliveSet

pub fn new(row_count: u32) -> Self

Creates a segment state in which every document is alive.

pub const fn row_count(&self) -> u32

Returns the immutable segment row count.

pub fn tombstone(&mut self, document: u32) -> Result<bool, AliveError>

Marks one live document as tombstoned.

Returns true only for the first tombstone of that identifier.

pub fn is_alive(&self, document: u32) -> bool

Returns whether a document is currently alive.

pub fn alive_bitmap(&self) -> &DocBitmap

Returns the live-document bitmap.

pub fn tombstone_bitmap(&self) -> &DocBitmap

Returns the tombstone bitmap.

pub fn live_count(&self) -> u64

Returns the exact live-document count.

pub fn tombstone_count(&self) -> u64

Returns the exact tombstone count.

pub fn iter_alive(&self) -> impl Iterator<Item = u32> + '_

Iterates live document identifiers in ascending order.

pub fn debug_assert_consistent(&self)

Audits the disjoint-union counter invariant in debug builds.
