/// This trait defines the actions that can be preformed with terminal color.
/// This trait can be implemented so that a concrete implementation of the ITerminalColor can fulfill
/// the wishes to work on an specific platform.
///
/// ## For example:
///
/// This trait is implemented for `WinApi` (Windows specific) and `ANSI` (Unix specific),
/// so that color-related actions can be performed on both UNIX and Windows systems.
trait ITerminalColor {
    /// Set the foreground color to the given color.
    fn set_fg(&self, fg_color: Color) -> Result<()>;
    /// Set the background color to the given color.
    fn set_bg(&self, fg_color: Color) -> Result<()>;
    /// Reset the terminal color to default.
    fn reset(&self) -> Result<()>;
    /// Gets an value that represents an color from the given `Color` and `ColorType`.
    fn color_value(&self, cored: Colored) -> String;
}

/// This could be used to style a type who is implementing `Display` with colors and attributes.
///
/// # Example
/// ```rust
/// // get an styled object which could be painted to the terminal.
/// let styled_object = style("Some Blue colored text on black background")
///     .with(Color::Blue)
///     .on(Color::Black);
///
/// // print the styled font * times to the current screen.
/// for i in 1..10
/// {
///     println!("{}", styled_object);
/// }
/// ```
///
/// # Important Remark
///
/// - Please checkout the documentation for `Colorizer` or `Styler`.
/// Those types will make it a bit easier to style a string.
