Macro freya::hooks::theme_with

macro_rules! theme_with {
    ($theme_name:ident {
        $(
            $theme_field_name:ident: $theme_field_val:expr,
        )*
    }) => { ... };
}

Create FooThemeWith structs without having to deal with the verbose syntax.

Examples

Without the macro:

render! {
    Button {
        theme: ButtonThemeWith {
            background: "blue".into(),
            font_theme: FontThemeWith {
                color: "white".into(),
                ..Default::default()
            }.into(),
            ..Default::default()
        }
    }
}

With the macro:

render! {
    Button {
        theme: theme_with!(ButtonTheme {
            background: "blue",
            font_theme: theme_with!(FontTheme {
                color: "white",
            }),
        })
    }
}
