Struct TaskAssignment 

pub struct TaskAssignment {
    pub task_id: String,
    pub context: Option<TaskContext>,
    pub heartbeat_interval_secs: u32,
    pub task: Option<Task>,
}

A task dispatched to a worker for execution or discovery.

For queue-based transports (NATS JetStream, etc.), workers should acknowledge the queue message immediately upon receipt — before calling TaskHeartbeat or executing the component. The orchestrator is the single source of truth for task lifecycle; queue-level redelivery would conflict with the orchestrator’s timeout and retry tracking. See the ack semantics documentation in the NATS transport.

Fields

task_id: String

Unique ID for this task assignment. Used to correlate completion reports with assignments.

context: Option<TaskContext>

Per-task context for worker callbacks (CompleteTask, SubmitRun, etc.). Contains the orchestrator URL that owns the current run.

heartbeat_interval_secs: u32

Suggested heartbeat interval in seconds. The worker should send TaskHeartbeat at this cadence after calling TaskHeartbeat. The orchestrator uses a 5s crash-detection timeout — if no heartbeat or CompleteTask arrives within 5s, the task is treated as failed. 0 means no heartbeating required.

task: Option<Task>

The task to perform — either a component execution or a discovery request.

Trait Implementations

impl Clone for TaskAssignment

fn clone(&self) -> TaskAssignment

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for TaskAssignment

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

Formats the value using the given formatter.

impl Default for TaskAssignment

fn default() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for TaskAssignment

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Message for TaskAssignment

fn encoded_len(&self) -> usize

Returns the encoded length of the message without a length delimiter.

fn clear(&mut self)

Clears the message, resetting all fields to their default.

fn encode(&self, buf: &mut impl BufMut) -> Result<(), EncodeError>

where Self: Sized,

Encodes the message to a buffer.

fn encode_to_vec(&self) -> Vec<u8>

where Self: Sized,

Encodes the message to a newly allocated buffer.

fn encode_length_delimited( &self, buf: &mut impl BufMut, ) -> Result<(), EncodeError>

where Self: Sized,

Encodes the message with a length-delimiter to a buffer.

fn encode_length_delimited_to_vec(&self) -> Vec<u8>

where Self: Sized,

Encodes the message with a length-delimiter to a newly allocated buffer.

fn decode(buf: impl Buf) -> Result<Self, DecodeError>

where Self: Default,

Decodes an instance of the message from a buffer.

fn decode_length_delimited(buf: impl Buf) -> Result<Self, DecodeError>

where Self: Default,

Decodes a length-delimited instance of the message from the buffer.

fn merge(&mut self, buf: impl Buf) -> Result<(), DecodeError>

where Self: Sized,

Decodes an instance of the message from a buffer, and merges it into self.

fn merge_length_delimited(&mut self, buf: impl Buf) -> Result<(), DecodeError>

where Self: Sized,

Decodes a length-delimited instance of the message from buffer, and merges it into self.

impl PartialEq for TaskAssignment

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

impl Serialize for TaskAssignment

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
