If successful, returns Ok((width, height)).
Error
This function will return an error if the output stream is not actually connected to a TTY instance, or if querying the TTY instance fails.
fn set_raw(&mut self, raw: bool) -> IoResult<()>
Controls whether this output stream is a "raw stream" or simply a normal stream.
Error
This function will return an error if the output stream is not actually connected to a TTY instance, or if querying the TTY instance fails.
