Module ockam_node::storage

Support for storing persistent values

Structs

• FileKeyValueStorage
  Key value storage backed by a file An additional cache in used to access values in memory and avoid re-reading the file too frequently
• FileValueStorage
  File Storage There three files involved
• InMemoryKeyValueStorage
  In memory implementation of a key / value storage
• InMemoryValueStorage
  In memory implementation of a value storage

Enums

• ValueStorageError
  Represents the failures that can occur when storing values

Traits

• KeyValueStorage
  This trait defines a key/value storage
• ToStringKey
  This trait needs to be implemented by structs which are used as keys in a key/value file This constraint is necessary due to the persistence of values as JSON in the underlying FileValueStorage
• ValueStorage
  This trait defines a storage interface for serializable values It uses a closures in its interface in order to support a transactional behaviour and recovery from errors. If the closure does not return a successful value then no change is performed
