car-eventlog

Append-only event log with JSONL persistence for the Common Agent Runtime.

What it does

Records every runtime operation as a typed event with optional JSONL journal persistence. Supports filtering by event kind and action ID, trace spans with parent-child relationships, and OTLP-compatible trace export. Journals can be reloaded for replay and audit.

Usage

use car_eventlog::{EventLog, EventKind, SpanStatus};
use std::collections::HashMap;

let mut log = EventLog::with_journal("/tmp/events.jsonl".into());
log.append(EventKind::ActionSucceeded, Some("a1"), Some("p1"), HashMap::new());

let span_id = log.begin_span("tool.call", "trace-1", None, HashMap::new());
log.end_span(&span_id, SpanStatus::Ok);
