Function rep 

pub fn rep<A: Clone + 'static + FromStr, F, G>(
    vm: &mut RoundVM,
    init: F,
    fun: G,
) -> A
where
    F: Fn(&mut RoundVM) -> A,
    G: Fn(&mut RoundVM, A) -> A,

Iteratively updates the value of the input expression at each device using the last computed value.

Arguments

• vm the current VM
• init the initial value
• fun the function to apply to the value

Generic Parameters

• A The type of value returned by the expression.
• F - The type of the closure, which must be a closure that takes no arguments and returns a value of type A.
• G - The type of the closure, which must be a closure that takes a tuple (RoundVM, A) and returns a tuple (RoundVM, A).

Returns

the updated value
