Feature request: `try_collect_vec()`

[amab8901]

Same as try_collect() except that I don't have to specify Vec<_> as a type parameter

[Philippe-Cholet]

This might be done as part of #844. It might be named maybe_collect_vec and could be called on Iterator<Item = Option<T>> and on Iterator<Item = Result<T, E>> (and not just the second).

maybe_-prefixed to avoid any conflict with the stdlib which should own try_-prefixed methods.
Our try_collect is in conflict with nightly Rust.

[amab8901]

would be great to also have try_join() when the iterator has elements of type Result<String> or Result<&str>!

[Philippe-Cholet]

We probably won't add many maybe_/try_ methods.

But there is .process_results(|it| it.join()) that should work for your use case.
