Is a Peekable of a Dynamic Iterator of i32 Expressible in Rust?

I have the following struct:

struct Quads<'a> {
    mx: &'a Vec<Vec<u32>>,
    xs: &'a mut Peekable<Range<i32>>,
    ys: &'a mut Peekable<Range<i32>>,
    dx: i32,
    dy: i32,
}

I want to know if it is possible to express a Peekable of a dynamic Iterator of i32 in Rust.

Yes, it is possible to express a Peekable of a dynamic Iterator of i32 in Rust. The Peekable type can be used with any iterator that implements the Iterator trait, including dynamic iterators generated by Range. In this case, the Peekable is being used with a Range<i32> iterator.
