Struct tokio::task::futures::TaskLocalFuture
source · pub struct TaskLocalFuture<T, F>where
T: 'static,{ /* private fields */ }
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.
Created by the function LocalKey::scope
.
Examples
tokio::task_local! {
static NUMBER: u32;
}
NUMBER.scope(1, async move {
println!("task local value: {}", NUMBER.get());
}).await;
