oryx.core.ppl.make_effect_handler(
    handlers: Dict[jax_core.Primitive, oryx.core.ppl.LogProbFunction]
) -> Callable[[Callable[..., Any]], Callable[..., Any]]

Args
handlers	A dict that maps JAX primitives to callback functions that take in (state, *args) and return (output, new_state). When running the the transformed function, the execution of primitives in handlers will be delegated to the callback functions rather than their default execution rules.

Returns
A function transformation that applies the handlers to an input function. The transformation takes in an input function and returns a transformed function that takes an additional initial state argument and returns an additional output state.
