Struct HandlePayload 

#[non_exhaustive]
pub struct HandlePayload {
    pub execution_id: ExecutionId,
    pub attempt_index: AttemptIndex,
    pub attempt_id: AttemptId,
    pub lease_id: LeaseId,
    pub lease_epoch: LeaseEpoch,
    pub lease_ttl_ms: u64,
    pub lane_id: LaneId,
    pub worker_instance_id: WorkerInstanceId,
}

Decoded view of an encoded HandleOpaque — the minimum set of fields every backend needs to construct its per-op KEYS + ARGV.

#[non_exhaustive]: fields grow additively when new attempt-cookie state lands (e.g. a Wave-5 partition routing hint). Construct via HandlePayload::new; field-access is via the pub fields.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

execution_id: ExecutionId

attempt_index: AttemptIndex

attempt_id: AttemptId

lease_id: LeaseId

lease_epoch: LeaseEpoch

lease_ttl_ms: u64

lane_id: LaneId

worker_instance_id: WorkerInstanceId

Implementations

impl HandlePayload

pub fn new( execution_id: ExecutionId, attempt_index: AttemptIndex, attempt_id: AttemptId, lease_id: LeaseId, lease_epoch: LeaseEpoch, lease_ttl_ms: u64, lane_id: LaneId, worker_instance_id: WorkerInstanceId, ) -> Self

Construct a payload. All fields are mandatory at Wave 1c — the #[non_exhaustive] guard lets future fields land additively.

Trait Implementations

impl Clone for HandlePayload

fn clone(&self) -> HandlePayload

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for HandlePayload

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

Formats the value using the given formatter.

impl PartialEq for HandlePayload

fn eq(&self, other: &HandlePayload) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
