Enum JoinError 

#[non_exhaustive]
pub enum JoinError {
    Cancelled,
    Aborted,
    Panicked,
    Empty,
    Unknown,
}

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Cancelled

The task was cancelled without an explicit abort request through its JoinHandle, such as during runtime shutdown.

Aborted

The task was cancelled after JoinHandle::abort was requested.

Panicked

The task panicked.

Empty

The task that was polled was empty or contained no pending future.

Unknown

Unknown error.
