struct

Resource

pub struct Resource {
    pub data: Signal<Value>,
    pub loading: Signal<bool>,
    pub error: Signal<Option<String>>,
}

Loading state for templates: bind it with [Resource::bind] and fill it with weft::web::load (or [Resource::set]).

let posts = Resource::new();
weft::web::load(&posts, async move { wp.posts(&query).send().await });
posts.bind(Scope::new(), "posts")
// template: if posts_loading { Skeleton } else if posts_error { Alert … } else { for p in posts { … } }

loading
