Types

StorageAdapter

</>

Trusted key/value primitives, including mutable branch pointers. Untrusted immutable content must use insert_content, not insert directly.

pub type StorageAdapter {
  StorageAdapter(
    insert: fn(identity.DefinitionRef, BitArray) -> Result(
      Nil,
      StorageError,
    ),
    lookup: fn(identity.DefinitionRef) -> Result(
      option.Option(BitArray),
      StorageError,
    ),
    delete: fn(identity.DefinitionRef) -> Result(
      Nil,
      StorageError,
    ),
    list_refs: fn() -> Result(
      List(identity.DefinitionRef),
      StorageError,
    ),
    close: fn() -> Result(Nil, StorageError),
  )
}
