Expand description

A snapshot of the current state of sync. Useful for displaying the status of sync to a user / consumer.

Fields§

§scan_ranges: Vec<ScanRange>§sync_start_height: BlockHeight§session_blocks_scanned: u32§total_blocks_scanned: u32§total_blocks: u32§session_sapling_outputs_scanned: u32§total_sapling_outputs_scanned: u32§session_orchard_outputs_scanned: u32§total_orchard_outputs_scanned: u32§session_ironwood_outputs_scanned: u32§total_ironwood_outputs_scanned: u32§total_outputs_scanned: u64

Numerator of the exact scan-progress ratio: outputs scanned so far across every shielded pool. Never exceeds total_outputs: the sync engine extends the tree bounds to each newly mined block under the wallet lock before it scans that block.

§total_outputs: u64

Denominator of the exact scan-progress ratio: outputs in the chain between the wallet birthday and the last known chain height, across every shielded pool. Zero when sync has never started, and also when the range from birthday to chain height contains no shielded outputs.

Implementations§

Source§

impl SyncStatus

Source

pub fn is_complete(&self) -> bool

Whether sync is complete: sync has started and every scan range is fully processed (ScanPriority::Scanned), so no range still awaits scanning, nullifier mapping, or nullifier refetching.

This is the sync task’s own terminal condition, so it holds even when the birthday-to-chain-height range contains no shielded outputs and the output ratio is vacuously 0 / 0.
