Struct TableScanPlan 

pub struct TableScanPlan { /* private fields */ }

A serializable, fixed global-snapshot scan plan for one typed table.

A plan does not retain the snapshot against expiration; applications keep the referenced global and shard snapshots available for their workers.

Implementations

impl TableScanPlan

pub fn snapshot_id(&self) -> u64

Return the fixed global snapshot selected for this scan.

pub fn total_buckets(&self) -> u32

Return the bucket count fixed by the global snapshot.

pub fn schema(&self) -> &TableSchema

Return the schema fixed into this plan.

pub fn data_size_bytes(&self) -> u64

Return the total encoded data size reported by all shard snapshots.

pub fn splits(&self) -> Result<Vec<TableScanSplit>>

Produce one independently serializable split per shard snapshot.
