Function wait_for_enter 

pub fn wait_for_enter(prompt: &str) -> PromptOutcome

Prints prompt to stdout and waits for Enter.

Does nothing and returns PromptOutcome::NotATty unless both stdin and stdout are terminals, so piped input is never swallowed by a prompt and nothing waits on a prompt that nobody can see. The prompt may contain ANSI styling; it is stripped when stdout does not want colour. See the module documentation for how Ctrl-C is handled.
