Struct AsyncSortedBatchBuilder

Source

pub struct AsyncSortedBatchBuilder<S: AsyncStore> { /* private fields */ }

Expand description

Memory-bounded async builder for entries already sorted by key.

Finalized node batches are published as they are emitted. Those nodes remain unreachable until AsyncSortedBatchBuilder::build returns the root.

Implementations§

Source §

impl<S> AsyncSortedBatchBuilder<S>
where S: AsyncStore, S::Error: Send + Sync,

Source

pub fn new(store: S, config: Config) -> Self

Create a memory-bounded async sorted builder.

Source

pub async fn add(&mut self, key: Vec<u8>, val: Vec<u8>) -> Result<(), Error>

Add the next nondecreasing key/value pair.

Duplicate keys replace the pending value. A decreasing key is rejected before it can publish any node derived from that key.

Source

pub async fn build(self) -> Result<Tree, Error>

Finish and publish the remaining nodes, then return the visible root.
