The actual amount of free space the vault has available.
def get_vault_free_space() -> int: ...
vault_free_space = property(get_vault_free_space, None)
This property reflects the actual amount of free space, in bytes, that the vault has available currently. A vault's actual free space is based on its actual size, which is reflected by the vault_size property.
Applications can also determine the maximum amount of free space the vault could possibly have by querying the possible_free_space property; please refer to its documentation, as well as the Vault Size topic, for more information.
This property is read-only.
