Function freya::prelude::use_future

pub fn use_future<T, F, D>(
    cx: &ScopeState,
    dependencies: D,
    future: impl FnOnce(<D as UseFutureDep>::Out) -> F
) -> &UseFuture<T>where
    T: 'static,
    F: Future<Output = T> + 'static,
    D: UseFutureDep,

A future that resolves to a value.

This runs the future only once - though the future may be regenerated through the UseFuture::restart method.

This is commonly used for components that cannot be rendered until some asynchronous operation has completed.

Whenever the hooks dependencies change, the future will be re-evaluated. If a future is pending when the dependencies change, the previous future will be canceled before the new one is started.

• dependencies: a tuple of references to values that are PartialEq + Clone
