///
/// ### Create a default text style
///
/// This example uses [`Font8x16`] and the [`Rgb565`] color space to create a default text style.
/// This will result in a white font with transparent background.
///
/// ```rust
/// use embedded_graphics::{
///     fonts::Font8x16,
///     pixelcolor::{Rgb565, RgbColor},
///     style::TextStyle,
///     text_style,
/// };
///
/// let style: TextStyle<Rgb565, _> = text_style!(font = Font8x16);
/// #
/// # assert_eq!(
/// #     style,
/// #     embedded_graphics::style::TextStyleBuilder::new(Font8x16).build()
/// # );
/// ```
///
/// ### Create colored text with background
///
/// This example uses [`Font6x8`] and the [`Rgb565`] color space to create a text style with red
/// text on a green background.
///
/// ```rust
/// use embedded_graphics::{
///     fonts::Font6x8,
///     pixelcolor::{Rgb565, RgbColor},
///     style::TextStyle,
///     text_style,
/// };
///
/// let style = text_style!(
///     font = Font6x8,
///     text_color = Rgb565::RED,
///     background_color = Rgb565::GREEN
/// );
/// #
/// # assert_eq!(
/// #     style,
/// #     embedded_graphics::style::TextStyleBuilder::new(Font6x8)
/// #         .text_color(Rgb565::RED)
/// #         .background_color(Rgb565::GREEN)
