using list of strings in Numba jitclass

Question

What is the proper way to include a list of strings in a Numba jitclass? The documentation here is very limited and I am currently encountering DeprecationWarnings.

Should I use an array of strings instead?

For example:

import numpy as np
from numba.experimental import jitclass
from numba import types


spec = [
    ('datetime', types.NPDatetime('s')),
    ('strings', types.List(types.unicode_type)),
]
@jitclass(spec)
class DateTimeStringClass:
    def __init__(self, datetime, strings):
        self.datetime = datetime
        self.strings = strings

# Example usage
datetime_obj = np.datetime64('2024-03-02 02:00:00')
string_list = ['string1', '323', 'string3']
obj = DateTimeStringClass(datetime_obj, string_list)
