Struct OrdValBatch 

pub struct OrdValBatch<L: Layout> {
    pub storage: OrdValStorage<L>,
    pub updates: usize,
}

The updates of a batch, as immutable update tuples.

The L parameter captures how the updates should be laid out.

Fields

storage: OrdValStorage<L>

The updates themselves.

updates: usize

The number of updates reflected in the batch.

We track this separately from storage because due to the singleton optimization, we may have many more updates than storage.updates.len(). It should equal that length, plus the number of singleton optimizations employed.

Trait Implementations

impl<'de, L: Layout> Deserialize<'de> for OrdValBatch<L>

where L::KeyContainer: Serialize + for<'a> Deserialize<'a>, L::ValContainer: Serialize + for<'a> Deserialize<'a>, L::OffsetContainer: Serialize + for<'a> Deserialize<'a>, L::TimeContainer: Serialize + for<'a> Deserialize<'a>, L::DiffContainer: Serialize + for<'a> Deserialize<'a>,

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl<L: Layout> Merger<OrdValBatch<L>> for OrdValMerger<L>

fn new( batch1: &OrdValBatch<L>, batch2: &OrdValBatch<L>, compaction_frontier: AntichainRef<'_, Time<L>>, ) -> Self

Creates a new merger to merge the supplied batches, optionally compacting up to the supplied frontier.

fn done(self) -> Option<OrdValBatch<L>>

Extracts merged results, absent if the merge cancelled to nothing.

fn work( &mut self, source1: &OrdValBatch<L>, source2: &OrdValBatch<L>, fuel: &mut isize, )

Perform some amount of work, decrementing fuel.

impl<L: Layout> Navigable for OrdValBatch<L>

type Cursor = OrdValCursor<L>
