Struct TaskHandle 

pub struct TaskHandle<T> { /* private fields */ }

Available on crate feature async only.

Opaque handle returned by Context::spawn.

Store the handle and pass it to Context::poll on subsequent frames to retrieve the task’s result. Dropping the handle cancels the in-flight task (via tokio::task::JoinHandle::abort), so keep it alive for as long as you care about the result.

The type parameter T ties the handle to the future’s output type so poll can downcast safely. Two handles never collide: each carries a unique id, so even two TaskHandle<String> live simultaneously route their results to the correct caller.

Requires the async feature.

Trait Implementations

impl<T> Debug for TaskHandle<T>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<T> Drop for TaskHandle<T>

fn drop(&mut self)

Executes the destructor for this type.

fn pin_drop(self: Pin<&mut Self>)

🔬This is a nightly-only experimental API. (pin_ergonomics)

Execute the destructor for this type, but different to Drop::drop, it requires self to be pinned.
