Struct RunState 

pub struct RunState {

    pub run_id: String,
    pub agent: String,
    pub status: Status,
    pub messages: Vec<Message>,
    pub steps: u32,
    pub usage: Usage,
    pub cost_usd: f64,
    pub pending: Vec<PendingCall>,
    pub approvals: HashMap<String, bool>,
    pub tool_results: Vec<Content>,
    pub structured_output: Option<Value>,
    pub finish_rejections: u32,
    pub next_seq: u64,
}

The full state of a run, derived purely from its events.

There is no other source of truth: live execution, resume after a crash and time-travel debugging all go through RunState::apply.

Fields

run_id: String

agent: String

status: Status

messages: Vec<Message>

steps: u32

usage: Usage

cost_usd: f64

pending: Vec<PendingCall>

approvals: HashMap<String, bool>

tool_results: Vec<Content>

Results gathered for the current batch of tool calls.

structured_output: Option<Value>

Validated final answer when the agent has a finish schema.

finish_rejections: u32

How many final answers have been rejected by the finish schema.

next_seq: u64

Implementations

impl RunState

pub fn from_events(events: &[Event]) -> Option<Self>

Rebuild state from a run’s events. Returns None for an empty slice. Pass a prefix (&events[..=n]) to see the state at any point in time.

pub fn apply(&mut self, event: &Event)

pub fn awaiting_approval(&self) -> Vec<PendingCall>
