impl str {

}

Prefix for a function that consumes an owned value and transforms it into a value of another type.
Not reinterpret cast! The data can be rearranged, reallocated, changed in any way, including losing information.
into_iter consumes a collection (like a vec, or a btreeset, or a hashmap) and produces an iterator over owned values, unlike iter and iter_mut which produce iterators over reference values.
