Struct ClaimPolicy 

#[non_exhaustive]
pub struct ClaimPolicy {
    pub max_wait: Option<Duration>,
    pub worker_id: WorkerId,
    pub worker_instance_id: WorkerInstanceId,
    pub lease_ttl_ms: u32,
}

Policy hints for claim. Carries the worker identity the backend needs to invoke ff_claim_execution (v0.7 Wave 2) plus the blocking-wait bound.

Wave 2 extension: worker_id + worker_instance_id + lease_ttl_ms are now required so the Valkey backend’s claim impl can issue the claim FCALL without a side-channel identity lookup. The constructor change is a pre-1.0 breaking change, tracked in the CHANGELOG.

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.

max_wait: Option<Duration>

Maximum blocking wait. None means backend-default (today: non-blocking / immediate return).

worker_id: WorkerId

Worker identity (stable across process restarts).

worker_instance_id: WorkerInstanceId

Worker instance identity (unique per process).

lease_ttl_ms: u32

Lease TTL in milliseconds for the claim about to be minted.

Implementations

impl ClaimPolicy

pub fn new( worker_id: WorkerId, worker_instance_id: WorkerInstanceId, lease_ttl_ms: u32, max_wait: Option<Duration>, ) -> Self

Build a claim policy. max_wait = None means non-blocking / immediate return. lease_ttl_ms is the TTL the backend installs on the minted lease.

Trait Implementations

impl Clone for ClaimPolicy

fn clone(&self) -> ClaimPolicy

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ClaimPolicy

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

Formats the value using the given formatter.

impl PartialEq for ClaimPolicy

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