Struct StoreOptions 

pub struct StoreOptions { /* private fields */ }

Options of a GridStore.

Implementations

impl StoreOptions

pub fn with_highlight(self, highlight: HighlightPolicy) -> Self

Sets the highlight policy, removal fade included. It belongs to the store, so every view over the store fades the same way.

pub fn with_publish_interval(self, interval: Duration) -> Self

Snapshots are published at most this often (default 8 ms, the same as a grid’s default pull interval, GridTuning::with_pull_interval), so writes arriving one by one are applied and published in batches.

A published snapshot shares every page with the store, so the next batch copies each page it writes to, about 15 µs per page of 1024 rows. Under a fast stream a batch writes to every page, and each publish costs a copy of the whole store: publishing more often than the grid pulls copies pages no grid reads. A shorter interval shows writes sooner in GridWriter::snapshot and GridWriter::flush; a longer one halves the ingest at 100k updates/s (16 ms against 8) and delays a write on screen by up to the interval.

pub fn with_write_coalescing(self, coalescing: WriteCoalescing) -> Self

How writes wait for the ingest (default WriteCoalescing::ByKey: an upsert takes the place of a waiting upsert of its key, so the queue grows with the keys written, not with the writes).

pub fn highlight(&self) -> HighlightPolicy

The highlight policy.

pub fn write_coalescing(&self) -> WriteCoalescing

How writes wait for the ingest.

pub fn publish_interval(&self) -> Duration

The minimum interval between published snapshots.
