#[autodiff]🔬This is a nightly-only experimental API. (
autodiff #124509)Expand description
Automatic Differentiation macro which allows generating a new function to compute
the derivative of a given function. It may only be applied to a function.
The expected usage syntax is
#[autodiff(NAME, MODE, INPUT_ACTIVITIES, OUTPUT_ACTIVITY)]
where:
NAME is a string that represents a valid function name.
MODE is any of Forward, Reverse, ForwardFirst, ReverseFirst.
INPUT_ACTIVITIES consists of one valid activity for each input parameter.
OUTPUT_ACTIVITY must not be set if we implicitely return nothing (or explicitely return
-> ()). Otherwise it must be set to one of the allowed activities.
