Module radix_substate_store_interface::interface

Structs

• DatabaseUpdates
  A canonical description of all database updates to be applied. Note: this struct can be migrated to an enum if we ever have a need for database-wide batch changes (see PartitionDatabaseUpdates enum).
• DbPartitionKey
  A database-level key of an entire partition. Seen from the higher-level API: it represents a pair (RE Node ID, Module ID). Seen from the lower-level implementation: it is used as a key in the upper-layer tree of our two-layered JMT.
• DbSortKey
  A database-level key of a substate within a known partition. Seen from the higher-level API: it represents a local Substate Key. Seen from the lower-level implementation: it is used as a key in the Substate-Tier JMT.
• NodeDatabaseUpdates
  A canonical description of specific Node’s updates to be applied. Note: this struct can be migrated to an enum if we ever have a need for Node-wide batch changes (see PartitionDatabaseUpdates enum).

Enums

• DatabaseUpdate
  An update of a single substate’s value.
• PartitionDatabaseUpdates
  A canonical description of specific Partition’s updates to be applied.
• SubstateChange
  A change applied to a Substate - see PartitionDatabaseUpdates::get_substate_change. Technically, this is a 1:1 counterpart of DatabaseUpdate, but operating on references.

Traits

• CommittableSubstateDatabase
  A write interface between Track and a database vendor.
• ListableSubstateDatabase
  A partition listing interface between Track and a database vendor.
• SubstateDatabase
  A read interface between Track and a database vendor.

Type Aliases

• DbNodeKey
• DbPartitionNum
• DbSubstateKey
  A fully-specified key of a substate (i.e. specifying its partition and sort key).
• DbSubstateValue
  A raw substate value stored by the database.
• PartitionEntry
  A key-value entry of a substate within a known partition.
