Struct css_in_rs::StyleProvider

pub struct StyleProvider<T> { /* private fields */ }

Manages dynamically inserted styles. You should usually have exactly one. Generated classnames are only unique for a fixed StyleProvider.

You will typically use StyleProvider in comination with the crate::make_styles! macro.

Example

make_styles! {
    (_theme: EmptyTheme) -> MyClasses {
        ".my_class > span" {
            color: "red",
        },
    }
}

fn main() {
    let elem: &web_sys::Element = todo!(); // Some element
    let style_provider = StyleProvider::new_and_mount(elem, EmptyTheme);
     
    // inject the css styles
    let cls = style_provider.add_classes::<MyClasses>();
    elem.set_class_name(&cls.my_class);
     
    // inject it again; no change; will return the same classes
    let cls2 = style_provider.add_classes::<MyClasses>();
    assert_eq!(cls.my_class, cls2.my_class);
}
