Enum AgentState 

pub enum AgentState {
    Cold,
    Starting,
    Idle,
    Working,
    Paused,
    Draining,
    Stopped,
    Error,
}

Agent lifecycle state.

Follows RAR worker lifecycle: cold → starting → idle → working → draining → stopped

                    work arrives
        Cold ─────────────────────→ Starting → Idle ⇄ Working

         │ idle timeout                         │ graceful shutdown
         │                                      ↓
         └──────────── Stopped ←──────────── Draining

Variants

Cold

Agent is registered but no process is running (scale-to-zero state). When work arrives for a Cold agent, the orchestrator needs to start a process.

Starting

Agent is starting up

Idle

Agent is idle, waiting for work

Working

Agent is working on a task

Paused

Agent is paused

Draining

Agent is finishing its current task but won’t accept new work. Used during graceful shutdown, rolling deploys, or idle timeout. Transitions to Stopped after current task completes.

Stopped

Agent has stopped

Error

Agent encountered an error

Implementations

impl AgentState

pub fn is_terminal(&self) -> bool

Check if agent is in a terminal state.

pub fn can_accept_work(&self) -> bool

Check if agent can accept new work.

pub fn is_active(&self) -> bool

Check if agent is in an active (process running) state.

pub fn emoji(&self) -> &'static str

Get emoji representation for display.

Trait Implementations

impl Clone for AgentState

fn clone(&self) -> AgentState

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for AgentState

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

Formats the value using the given formatter.

impl Default for AgentState

fn default() -> AgentState

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for AgentState

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for AgentState

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

Formats the value using the given formatter.

impl PartialEq for AgentState

fn eq(&self, other: &AgentState) -> 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 AgentState

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Copy for AgentState

impl Eq for AgentState
