Query

Struct Query 

Source
pub struct Query<'a, T, E, F: Fn()> {
    pub data: &'a ReadSignal<QueryData<Rc<T>, Rc<E>>>,
    pub status: Rc<Signal<Status>>,
    pub refetch: &'a F,
}
Expand description

The struct representing a query

§Example

let Query { data, status, refetch } = use_query(
    cx,
    ("hello", "World"),
    || async { Result::<_, ()>::Ok("World".to_string()) }
);

Fields§

§data: &'a ReadSignal<QueryData<Rc<T>, Rc<E>>>

The data returned by the query. See QueryData.

§status: Rc<Signal<Status>>

The status of the query. See Status.

§refetch: &'a F

A function to trigger a refetch of the query and all queries with the same key.
