async-reify

Instrument async functions to extract their continuation structure as an inspectable, serializable step graph.

The core workflow:

1. Wrap futures in [TracedFuture] to record [PollEvent]s
2. Use [LabeledFuture] to attach source labels to await points
3. Extract an [AsyncStepGraph] from the collected trace
4. Optionally serialize to JSON or render as Graphviz DOT

Examples

use async_reify::{TracedFuture, PollResult};

# tokio_test::block_on(async {
let (result, trace) = TracedFuture::run(async { 42 }).await;
assert_eq!(result, 42);
assert!(!trace.events.is_empty());
assert!(matches!(trace.events.last().unwrap().result, PollResult::Ready));
# });
