Function bdrck::cli::prompt_for_string

pub fn prompt_for_string<IS: AbstractStream, OS: AbstractStream>(
    input_stream: IS, 
    output_stream: OS, 
    prompt: &str, 
    is_sensitive: bool
) -> Result<String>

Prompt the user for a string (read from the given input stream) using the given output stream (typically standard output or standard error) to display the given prompt message.

If is_sensitive is true, then the users characters will not be echoed back (e.g. this will behave like a password prompt).

Note that there are various requirements for the given streams, and this function will return an error if any of them are not met:

• Both input_stream and output_stream must be TTYs.
• input_stream must return a valid Read instance.
• output_stream must return a valid Write instance.
