Some example code not showing in rustdoc

[mcast]

Following #rust conversation with kimundi (just now from about 11:18pm +01:00), I found a useful example in the source,

    /// Takes each element in the `Iterator`: if it is an `Err`, no further
    /// elements are taken, and the `Err` is returned. Should no `Err` occur, a
    /// container with the values of each `Result` is returned.
    ///
    /// Here is an example which increments every integer in a vector,
    /// checking for overflow:

but it seems not to be rendered anywhere on doc.rust-lang.org .

Or at least, search engines aren't finding the text (refresh too slow?), and it isn't where I look for it (I'm hopelessly lost?).

Thanks @eefriedman, this is a dup.
