AwaitProps

Struct AwaitProps 

Source
pub struct AwaitProps<T, Fut, Chil, V>
where T: Send + Sync + Serialize + DeserializeOwned + 'static, Fut: Future<Output = T> + Send + 'static, Chil: FnOnce(&T) -> V + Send + 'static, V: IntoView + 'static,
{ pub future: Fut, pub blocking: bool, pub children: Chil, }
Expand description

Props for the Await component.

Allows you to inline the data loading for an async block or server function directly into your view. This is the equivalent of combining a [create_resource] that only loads once (i.e., with a source signal || ()) with a Suspense with no fallback.

Adding let:{variable name} to the props makes the data available in the children that variable name, when resolved.

async fn fetch_monkeys(monkey: i32) -> i32 {
    // do some expensive work
    3
}

view! {
    <Await
        future=fetch_monkeys(3)
        let:data
    >
        <p>{*data} " little monkeys, jumping on the bed."</p>
    </Await>
}

§Required Props

  • future: [Fut]
    • A Future that will the component will .await before rendering.
  • children: [Chil]
    • A function that takes a reference to the resolved data from the future renders a view.

      §Syntax

      This can be passed in the view children of the <Await/> by using the let: syntax to specify the name for the data variable.

      view! {
          <Await
              future=fetch_monkeys(3)
              let:data
          >
              <p>{*data} " little monkeys, jumping on the bed."</p>
          </Await>
      }

      is the same as

      view! {
         <Await
             future=fetch_monkeys(3)
             children=|data| view! {
               <p>{*data} " little monkeys, jumping on the bed."</p>
             }
         />
      }

§Optional Props

  • blocking: bool
    • If true, the component will create a blocking resource, preventing the HTML stream from returning anything before future has resolved.

Fields§

§future: Fut

A Future that will the component will .await before rendering.

§blocking: bool

If true, the component will create a blocking resource, preventing the HTML stream from returning anything before future has resolved.

§children: Chil

A function that takes a reference to the resolved data from the future renders a view.

§Syntax

This can be passed in the view children of the <Await/> by using the let: syntax to specify the name for the data variable.

view! {
    <Await
        future=fetch_monkeys(3)
        let:data
    >
        <p>{*data} " little monkeys, jumping on the bed."</p>
    </Await>
}

is the same as

view! {
   <Await
       future=fetch_monkeys(3)
       children=|data| view! {
         <p>{*data} " little monkeys, jumping on the bed."</p>
       }
   />
}
