Decorator to wrap callable with memoizing function using cache. Repeated calls with the same arguments will lookup result in cache and avoid function evaluation. If name is set to None (default), the callable name will be determined automatically. If typed is set to True, function arguments of different types will be cached separately. For example, f(3) and f(3.0) will be treated as distinct calls with distinct results. The original underlying function is accessible through the __wrapped__ attribute. This is useful for introspection, for bypassing the cache, or for rewrapping the function with a different cache. >>> from diskcache import Index >>> mapping = Index() >>> @mapping.memoize() ... def fibonacci(number): ... if number == 0: ... return 0 ... elif number == 1: ... return 1 ... else: ... return fibonacci(number - 1) + fibonacci(number - 2) >>> print(fibonacci(100)) 354224848179261915075 An additional `__cache_key__` attribute can be used to generate the cache key used for the given arguments. >>> key = fibonacci.__cache_key__(100) >>> print(mapping[key]) 354224848179261915075 Remember to call memoize when decorating a callable.
