Functions
checkpoint​
Checkpoint a function call. If the function has already been called with the same arguments, it will return the result from the cache.Parameters
func
(Callable
[...
,~T
]) - The function to checkpointargs
(Any
) - The arguments to the functionidempotency_key
(Any
) - The extra key to change the function's idempotency, defaults to None Default:None
kwargs
(Any
) - The keyword arguments to the function
Returns
T
: The result of the function
make_deterministic​
Make an object deterministic by adding a checkpoint attribute to it. It's a no-op for primitive types and datetimes.Parameters
obj
(Any
) - The object to make idempotentkey_obj
(Any
) - The key object to generate the deterministic key for the object
Returns
Any
: The object with the checkpoint
with_checkpoint​
Decorator to checkpoint a function call. If the function has already been called with the same arguments, it will return the result from the cache.Parameters
func
(Optional
[Callable
[~P
,~T
]]) - The function to checkpoint Default:None
idempotency_key
(Any
) - The extra key to change the function's idempotency, defaults to None Default:None
Returns
Callable
[~P
, ~T
