DustCloudBackup

interface DustCloudBackup : DustCloudBackupSource

Full cross-device dust backup — adds the upload side to DustCloudBackupSource. One implementation serves both views: DustSyncManager consumes only fetch, MidnightWallet also drives upload.

Functions

Link copied to clipboard
abstract suspend fun fetch(address: String): RestoredDustCheckpoint?

The cloud checkpoint for address, or null if none / unavailable.

Link copied to clipboard
abstract suspend fun upload(address: String, stateBytes: ByteArray, lastEventId: Long)

Snapshot this address's checkpoint into the (multi-network) cloud bundle, preserving other networks' entries. Best-effort + idempotent: a content hash skips re-upload when nothing changed. Callers wrap in runCatching so a backup failure never affects wallet operations.
