Struct WorkerStatus 

pub struct WorkerStatus {
    pub id: WorkerId,
    pub address: String,
    pub capabilities: Capabilities,
    pub load: Option<LoadMetrics>,
    pub active_plans: Vec<String>,
    pub last_heartbeat: DateTime<Utc>,
    pub connected: bool,
}

Status of a registered worker.

Fields

id: WorkerId

The worker’s unique id, as it registered itself.

address: String

Where clients reach the worker (e.g. ws://host:8080). The coordinator hands this out on /submit and steps aside — the plan and its tensor payloads travel client→worker direct, never through the coordinator.

capabilities: Capabilities

What the worker offers: CPUs, RAM, GPUs, Python envs, tags. Placement matches required tags against these via matches_tags.

load: Option<LoadMetrics>

Load reported with the latest heartbeat; None until the first one arrives after registration.

active_plans: Vec<String>

The plans currently leased to this worker. /submit takes a lease (WorkerRegistry::claim), /complete releases it (WorkerRegistry::release) — this list is what makes has_capacity and the least-loaded tie-break mean anything.

last_heartbeat: DateTime<Utc>

When the worker last beat (workers beat every 10s). What is_alive and the reaper compare against.

connected: bool

False after an explicit WorkerRegistry::disconnect; re-registering sets it back. A disconnected worker is never alive, however fresh its heartbeat.

Implementations

impl WorkerStatus

pub fn has_capacity(&self, max_concurrent: usize) -> bool

Whether the worker has capacity for more work.

pub fn matches_tags(&self, required: &[String]) -> bool

Whether the worker matches a set of required tags.

pub fn is_alive(&self, timeout_secs: i64) -> bool

Whether the worker is considered alive (heartbeat within timeout).
