A trait for minimal terminal-like behavior.

Anything that implements this trait can be used a draw target via ProgressDrawTarget::term_like.

Required Methods

fn width(&self) -> u16

Return the terminal width

fn move_cursor_up(&self, n: usize) -> Result<(), Error>

Move the cursor up by n lines

fn move_cursor_down(&self, n: usize) -> Result<(), Error>

Move the cursor down by n lines

fn move_cursor_right(&self, n: usize) -> Result<(), Error>

Move the cursor right by n chars

fn move_cursor_left(&self, n: usize) -> Result<(), Error>

Move the cursor left by n chars

fn write_line(&self, s: &str) -> Result<(), Error>

Write a string and add a newline.

fn write_str(&self, s: &str) -> Result<(), Error>

Write a string

fn clear_line(&self) -> Result<(), Error>

Clear the current line and reset the cursor to beginning of the line

fn flush(&self) -> Result<(), Error>

Provided Methods

fn height(&self) -> u16

Return the terminal height
