Trait Style

Source 
pub trait Style: Sized {
    // Required method
    fn default_style() -> StyleBuilder<Self>;
}
Expand description

A trait implemented by styles.

This will allow the style to be used in the arguments of StyleBuilder functions.

§Example

struct MyStyle {
    my_color: Color,
    my_padding: Padding,
}

impl Style for MyStyle {
    fn default_style() -> StyleBuilder<Self> {
        StyleBuilder::new(|theme: &Theme, button: &ButtonStyle| {
            MyStyle {
                my_color: theme.accent,
                my_padding: button.padding,
            }
        })
    }
}

let mut styles = Styles::new()
    .with(|| Theme {
        accent: Color::rgb(1.0, 0.0, 0.0),
        ..Theme::default()
    })
    .with(|theme: &Theme| ButtonStyle {
        padding: Padding::all(10.0),
        ..Default::default()
    });

let my_style = styles.style::<MyStyle>();

assert_eq!(my_style.my_color, Color::rgb(1.0, 0.0, 0.0));
assert_eq!(my_style.my_padding, Padding::all(10.0));

Required Methods§

Source

fn default_style() -> StyleBuilder<Self>

The default style of the object.

Dyn Compatibility§

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
