Function lambda_runtime::handler_fn

pub fn handler_fn<A, F, Fut>(f: F) -> ServiceFn<impl Fn(LambdaEvent<A>) -> Fut> where
    F: Fn(A, Context) -> Fut, 

👎 Deprecated since 0.5.0:

Use service_fn and LambdaEvent instead

Return a new ServiceFn with a closure that takes an event and context as separate arguments.
