pub struct TaskLocalFuture<T, F> where
    T: 'static, 
{ /* fields omitted */ }
Expand description

A future that sets a value T of a task local for the future F during its execution.

The value of the task-local must be 'static and will be dropped on the completion of the future.

    static NUMBER: u32;
}

NUMBER.scope(1, async move {
    println!("task local value: {}", NUMBER.get());
}).await;
