§

type Time = T

The type of time in frontiers to extract updates.
§

type Chunk = Vec<((K, V), T, R)>

The internal representation of chunks of data.
§

type Output = Vec<((K, V), T, R)>

The output type TODO: This should be replaced by Chunk or another container once the builder understands building from a complete chain.
source§

fn merge( &mut self, list1: Vec<Self::Chunk>, list2: Vec<Self::Chunk>, output: &mut Vec<Self::Chunk>, stash: &mut Vec<Self::Chunk>, )

Merge chains into an output chain.
source§

Extract ready updates based on the upper frontier.
source§

fn seal<B: Builder<Input = Self::Output, Time = Self::Time>>( chain: &mut Vec<Self::Chunk>, lower: AntichainRef<'_, Self::Time>, upper: AntichainRef<'_, Self::Time>, since: AntichainRef<'_, Self::Time>, ) -> B::Output

Build from a chain TODO: We can move this entirely to MergeBatcher once builders can accepts chains.
source§

fn account(chunk: &Self::Chunk) -> (usize, usize, usize, usize)

Account size and allocation changes. Returns a tuple of (records, size, capacity, allocations).
