Enum TaskState 

pub enum TaskState {
    Running,
    Settled(Value),
    Failed(RuntimeError),
    Cancelled,
}

What a spawned task has done so far.

Variants

Running

The body is running on its own thread, which has not been joined yet.

Settled(Value)

The body produced a value. Awaiting again returns the same value.

Failed(RuntimeError)

The body raised a RuntimeError. Awaiting again raises the same one.

Cancelled

The task was cancelled: its own flag was raised, and it stopped at the next safepoint rather than finishing. Awaiting a cancelled task is an error.
