Enum StorageTask

pub enum StorageTask {
    Load {
        key: StorageKey,
    },
    LoadRange {
        prefix: StorageKey,
    },
    Put {
        key: StorageKey,

Expand description

Represents storage operations that can be performed by both the main Samod instance and document actors.

StorageTask defines the common interface for all storage operations:

  • Single value operations (Load, Put, Delete)
  • Bulk operations (LoadRange)

This enum is used in two contexts:

  1. As part of IoAction::Storage(StorageTask) for the main Samod instance
  2. As part of DocumentIoTask for document actors

§Storage Model

Storage operations work with a simple key-value model:

  • Keys are represented by StorageKey
  • Values are arbitrary byte arrays
  • Range queries are supported via prefix matching

Variants§

§

Load

Load a single value from storage by its key.

This operation should retrieve the value associated with the given key from persistent storage. If the key doesn’t exist, the operation should complete successfully with a None result.

§Fields

  • key - The storage key to look up

Fields

§

LoadRange

Load all key-value pairs that have keys starting with the given prefix.

This operation performs a range query over the storage, returning all entries whose keys begin with the specified prefix. This is used for efficient bulk operations and queries over related data.

§Fields

  • prefix - The key prefix to match against

Fields

§prefix: StorageKey
§

Put

Store a key-value pair in persistent storage.

This operation should persist the given key-value pair to storage, replacing any existing value for the same key.

§Fields

  • key - The storage key
  • value - The data to store

Fields

§value: Vec<u8>
§

Delete

Remove a key-value pair from persistent storage.

This operation should remove the entry for the given key from storage. If the key doesn’t exist, the operation should complete successfully as a no-op.

§Fields

  • key - The storage key to remove
