Struct RunContext 

pub struct RunContext { /* private fields */ }

Run-scoped emitter state: the shared run_id and the run’s own clock.

Every event in a run repeats its run_id, and the lifecycle events carry elapsed_ms measured from the same origin, so an agent can stitch a run together from either stream without guessing. The id is derived from the process id and a monotonic start stamp: unique per run, cheap, and carrying nothing about the user’s text or filesystem — the CLI is stateless by default and the run id must not become a back door for run history.

Implementations

impl RunContext

pub fn with_id(run_id: impl Into<String>) -> Self

Adopt an explicit id — used by tests so assertions are not clock-dependent.

pub fn generate() -> Self

Derive a fresh id for this process invocation.

pub fn run_id(&self) -> &str

The id every event in this run repeats.

pub fn elapsed_ms(&self) -> u64

Milliseconds since the run began.

pub fn event(&self, event_type: EventType) -> Map<String, Value>

An object carrying the common fields plus this run’s id.

Trait Implementations

impl Debug for RunContext

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

Formats the value using the given formatter.
