Expand description

A terminal with similar capabilities to an ANSI Terminal (foreground/background colors etc).

Required Methods§

source

fn fg(&mut self, color: u32) -> Result<bool>

🔬This is a nightly-only experimental API. (test)

Sets the foreground color to the given color.

If the color is a bright color, but the terminal only supports 8 colors, the corresponding normal color will be used instead.

Returns Ok(true) if the color was set, Ok(false) otherwise, and Err(e) if there was an I/O error.

source

fn reset(&mut self) -> Result<bool>

🔬This is a nightly-only experimental API. (test)

Resets all terminal attributes and colors to their defaults.

Returns Ok(true) if the terminal was reset, Ok(false) otherwise, and Err(e) if there was an I/O error.

Note: This does not flush.

That means the reset command may get buffered so, if you aren’t planning on doing anything else that might flush stdout’s buffer (e.g., writing a line of text), you should flush after calling reset.
