    Class GenericAccountIndex

    GenericAccountIndex

    A wrapper around an AccountIndex, which is a shortened, variable-length encoding for an Account. We extends from [[U32]] to provide the number-like properties.

    Readonly__UIntType

    __UIntType: "u32" = 'u32'
    createdAtHash?: IU8a

    The block at which this value was retrieved/created (set to non-empty when retrieved from storage)

    encodedLength: number

    The length of the value when encoded as a Uint8Array

    initialU8aLength?: number

    The length of the initial encoded value (Only available when the value was constructed from a Uint8Array input)

    isStorageFallback?: boolean

    (internal usage) Indicates that the value was created via a fallback. This is used when with data specified in the metadata when the storage entry is empty.

    With metadata fallback values (available as defaults on most storage entries) any empty storage item should erturn the default. (This is the same as the implementation on the Bizinikiwi runtime)

    isUnsigned: boolean
    registry: Registry

    The registry associated with this object

    Static Optional Readonly__fallbackType

    __fallbackType?: string

    An internal fallback type (previous generation) if encoding fails
