Trait DisplayBackend 

pub trait DisplayBackend: Write {
    // Required methods
    fn set_attributes(&mut self, attributes: Attributes) -> Result<()>;
    fn set_fg(&mut self, color: Color) -> Result<()>;
    fn set_bg(&mut self, color: Color) -> Result<()>;

    // Provided method
    fn write_styled(&mut self, styled: &Styled<dyn Display + '_>) -> Result<()> { ... }
}
