Missing TryInto from usize to float

[jacksun007]

Currently there is no trait bound that will satisfy this very simple algorithm:

fn average<T>(list: &Vec<T>) -> T 
    where T: Div<Output=T> + Add<Output=T> + Default + TryFrom<usize>
{
    let mut total = Default::default();
    if list.len() == 0 {
        total
    }
    else {
        for val in list.iter() {
            total = total + *val;
        }
        total / TryFrom::try_from(list.len()).unwrap()
    }
}
