Function inplace_it::inplace_fixed_size_array

pub fn inplace_fixed_size_array<T: FixedArray, Result, Init: Fn(usize) -> T::Item, Consumer: Fn(&mut [T::Item]) -> Result>(
    init: Init,
    consumer: Consumer
) -> Result

inplace_fixed_size_array is used when inplace_array realize that the size of requested array of T is small enough and should be replaced on the stack.

It use inplace function to place the array on the stack and fills it up with help of init closure and then pass a reference to a slice of the vector into the consumer closure. consumer’s result will be returned.
