TypeError: cannot pickle 'generator' object

[Euraxluo]

code:

from rocksdict import Rdict

path = str("./test_dict")
db = Rdict(path)
def f(a, b):
    for n in range(a):
        yield b + b[-1] * n


gen = f(4, 'ay')
x = next(gen)
db['gx'] = gen

error:

TypeError: cannot pickle 'generator' object

thinking:

It should be the cause of pickling, but it doesn't fit the readme description of being able to store anything

[Euraxluo]

Default mode, which allows storing int, float, bool, str, bytes, and other python objects.

[Congyuwang]

Right, only python objects that can be pickled. But you might also use raw_mode to store objects in custom encoding.

[Euraxluo]

in history commit :value: int, float, bool, str, bytes and anything that supports pickle.

i will try,thx

Updated the readme, adding (with Pickle) to clarify this problem.
