sourcefn supports_color(&self) -> bool
fn supports_color(&self) -> bool
Returns true if and only if the underlying writer supports colors.
sourcefn set_color(&mut self, _: &ColorSpec) -> Result<()>
fn set_color(&mut self, _: &ColorSpec) -> Result<()>

fn reset(&mut self) -> Result<()>
Reset the current color settings to their original settings. Read more
sourcefn is_synchronous(&self) -> bool
fn is_synchronous(&self) -> bool
Returns true if and only if the underlying writer must synchronously
interact with an end user’s device in order to control colors. By
default, this always returns false
. Read more
