Struct RegisterWorkerArgs 

#[non_exhaustive]
pub struct RegisterWorkerArgs {
    pub worker_id: WorkerId,
    pub worker_instance_id: WorkerInstanceId,
    pub lanes: BTreeSet<LaneId>,
    pub capabilities: BTreeSet<String>,
    pub liveness_ttl_ms: u64,
    pub namespace: Namespace,
    pub now: TimestampMs,
}

Inputs to crate::engine_backend::EngineBackend::register_worker (RFC-025). Feature gate: core.

worker_instance_id is process identity (unique per-boot); worker_id is pool / logical identity (stable across restarts). See RFC-025 §7 terminology glossary.

liveness_ttl_ms is stored alongside the registration so heartbeat_worker refreshes to the same value without the caller re-supplying it.

Re-registering with the same worker_instance_id is idempotent (RFC-025 §9.3): caps/lanes/TTL overwritten, Refreshed returned. Re-registering with the same worker_instance_id under a DIFFERENT worker_id is rejected with Validation(InvalidInput, "instance_id reassigned").

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.

worker_id: WorkerId

worker_instance_id: WorkerInstanceId

lanes: BTreeSet<LaneId>

Workers serve one-or-more lanes. BTreeSet for stable iteration + dedup.

capabilities: BTreeSet<String>

liveness_ttl_ms: u64

Stored for subsequent heartbeat_worker TTL refresh.

namespace: Namespace

now: TimestampMs

Implementations

impl RegisterWorkerArgs

pub fn new( worker_id: WorkerId, worker_instance_id: WorkerInstanceId, lanes: BTreeSet<LaneId>, capabilities: BTreeSet<String>, liveness_ttl_ms: u64, namespace: Namespace, now: TimestampMs, ) -> Self

Trait Implementations

impl Clone for RegisterWorkerArgs

fn clone(&self) -> RegisterWorkerArgs

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for RegisterWorkerArgs

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

Formats the value using the given formatter.

impl PartialEq for RegisterWorkerArgs

fn eq(&self, other: &RegisterWorkerArgs) -> 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.
