A plain write object without color support

§

Stream

Color-enabled stdio, with information on whether color should be used

Fields

Implementations§

Source§

impl ShellOut

Source

fn message_stderr( &mut self, status: &dyn Display, message: Option<&dyn Display>, style: &Style, justified: bool, ) -> CargoResult<()>

Prints out a message with a status. The status comes first, and is bold plus the given color. The status can be justified, in which case the max width that will right align is 12 chars.

Source

fn stdout(&mut self) -> &mut dyn Write

Gets stdout as a io::Write.

Source

fn stderr(&mut self) -> &mut dyn Write

Gets stderr as a io::Write.
