Creating a vector via an iterator

Another way to create a vector is via an iterator. This is achieved via the collect() method:

let my_vec: Vec<u64> = (0..10).collect(); 

The format for the iterator is very convenient. Instead of the likes of let foo = {0,1,2,3};, this is shortened to use .., which means all numbers between a and b (b being excluded - so 0 .. 10 creates a vector containing 0,1,2,3,4,5,6,7,8,9). This can be seen in the source example supplied with this book.
