Retrieve actual stderr / stdout as string

[rcoh]

I'd like to do more complex validation and actually grab stdout/stderr as strings and do my own asserts on them. Is that possible? I wasn't able to find it in the docs.

Not at the moment. In the new api design I'm working on, I'm considering it.

[rcoh]

Ideally I'd just do:
assert_cli::Assert::main_binary().stdout().execute() and I'd get a string.

Addressed in assert_cmd
https://github.com/assert-rs/assert_cmd
assert_cli is going to morph into a wider-focused tool, including things like assert_fs. See #41
