Function term_size::dimensions_stderr

pub fn dimensions_stderr() -> Option<(usize, usize)>

Query the current processes's error output (stderr) only, in the attempt to dtermine terminal width. If that streams is actually a tty, this function returns its width and height as a number of characters.

Errors

If the stream is not a tty or return any errors this function will return None.

Example

To get the dimensions of your terminal window, simply use the following:

if let Some((w, h)) = term_size::dimensions_stderr() {
    println!("Width: {}\nHeight: {}", w, h);
} else {
    println!("Unable to get term size :(")
}
