Struct AwaitProps 

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,
}

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>
       }
   />
}

Implementations

impl<T, Fut, Chil, V> 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 fn builder() -> AwaitPropsBuilder<T, Fut, Chil, V>

Create a builder for building AwaitProps. On the builder, call .future(...), .blocking(...)(optional), .children(...) to set the values of the fields. Finally, call .build() to create the instance of AwaitProps.
