Struct BlockOnDeadlock 

pub struct BlockOnDeadlock {
    pub kind: BlockOnDeadlockKind,
    pub park_deadline: Option<Duration>,
}

Typed panic payload for a self-detected block_on deadlock. Thrown with std::panic::panic_any at the park DECISION (never merely on a Pending return, because a self-waking future is not a deadlock), so the runtime fails loudly instead of freezing the thread (and, in the CurrentThread-on-JS-thread case, the whole JS event loop, where not even test-harness timeouts can fire). When the panic unwinds out of a spawned task’s poll, JoinError::from_panic preserves this diagnostic’s message.

Fields

kind: BlockOnDeadlockKind

park_deadline: Option<Duration>

The armed deadline for the deadline-based kinds; None for the provable threadless case.
