Module lightning::util::persist

This module contains a simple key-value store trait KVStore that allows one to implement the persistence for ChannelManager, NetworkGraph, and ChannelMonitor all in one place.

Structs

• MonitorUpdatingPersister
  Implements Persist in a way that writes and reads both ChannelMonitors and ChannelMonitorUpdates.

Constants

• ARCHIVED_CHANNEL_MONITOR_PERSISTENCE_PRIMARY_NAMESPACE
  The primary namespace under which archived ChannelMonitors will be persisted.
• ARCHIVED_CHANNEL_MONITOR_PERSISTENCE_SECONDARY_NAMESPACE
  The secondary namespace under which archived ChannelMonitors will be persisted.
• CHANNEL_MANAGER_PERSISTENCE_KEY
  The key under which the ChannelManager will be persisted.
• CHANNEL_MANAGER_PERSISTENCE_PRIMARY_NAMESPACE
  The primary namespace under which the ChannelManager will be persisted.
• CHANNEL_MANAGER_PERSISTENCE_SECONDARY_NAMESPACE
  The secondary namespace under which the ChannelManager will be persisted.
• CHANNEL_MONITOR_PERSISTENCE_PRIMARY_NAMESPACE
  The primary namespace under which ChannelMonitors will be persisted.
• CHANNEL_MONITOR_PERSISTENCE_SECONDARY_NAMESPACE
  The secondary namespace under which ChannelMonitors will be persisted.
• CHANNEL_MONITOR_UPDATE_PERSISTENCE_PRIMARY_NAMESPACE
  The primary namespace under which ChannelMonitorUpdates will be persisted.
• KVSTORE_NAMESPACE_KEY_ALPHABET
  The alphabet of characters allowed for namespaces and keys.
• KVSTORE_NAMESPACE_KEY_MAX_LEN
  The maximum number of characters namespaces and keys may have.
• MONITOR_UPDATING_PERSISTER_PREPEND_SENTINEL
  A sentinel value to be prepended to monitors persisted by the MonitorUpdatingPersister.
• NETWORK_GRAPH_PERSISTENCE_KEY
  The key under which the NetworkGraph will be persisted.
• NETWORK_GRAPH_PERSISTENCE_PRIMARY_NAMESPACE
  The primary namespace under which the NetworkGraph will be persisted.
• NETWORK_GRAPH_PERSISTENCE_SECONDARY_NAMESPACE
  The secondary namespace under which the NetworkGraph will be persisted.
• OUTPUT_SWEEPER_PERSISTENCE_KEY
  The secondary namespace under which OutputSweeper state will be persisted. The key under which OutputSweeper state will be persisted.
• OUTPUT_SWEEPER_PERSISTENCE_PRIMARY_NAMESPACE
  The primary namespace under which OutputSweeper state will be persisted.
• OUTPUT_SWEEPER_PERSISTENCE_SECONDARY_NAMESPACE
  The secondary namespace under which OutputSweeper state will be persisted.
• SCORER_PERSISTENCE_KEY
  The key under which the WriteableScore will be persisted.
• SCORER_PERSISTENCE_PRIMARY_NAMESPACE
  The primary namespace under which the WriteableScore will be persisted.
• SCORER_PERSISTENCE_SECONDARY_NAMESPACE
  The secondary namespace under which the WriteableScore will be persisted.

Traits

• KVStore
  Provides an interface that allows storage and retrieval of persisted values that are associated with given keys.
• Persister
  Trait that handles persisting a ChannelManager, NetworkGraph, and WriteableScore to disk.

Functions

• read_channel_monitors
  Read previously persisted ChannelMonitors from the store.
