Struct TaskHandle 

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

Opaque, typed token for a node’s output.

A TaskHandle<T> provides compile-time type-safe access to a task’s output. You can:

1. Pass it to crate::TaskBuilder::depends_on to wire up dependencies
2. Use it with crate::DagOutput::get to retrieve the output after crate::DagRunner::run

Examples

let mut dag = DagRunner::new();
let node = dag.add_task(LoadValue::new(42));

let mut output = dag.run(|fut| async move { tokio::spawn(fut).await.unwrap() }).await.unwrap();

assert_eq!(output.get(node), 42);
