Today I m shipping RustAPI v0.1.300 with a new flagship feature: Replay (Time-Travel Debugging) a complete Record Replay Diff system for HTTP requests.
Why it matters
When a bug only happens in production, try to reproduce it becomes the bottleneck. With Replay, you can record real requests, replay them locally or in staging, and diff the new response vs the recorded one instantly.
What s included in v0.1.300
ReplayLayer middleware for automatic request/response recording
Stores: InMemoryReplayStore + FileSystemReplayStore
Admin HTTP routes to list, replay, and diff entries
ReplayClient for programmatic replay testing
Security: disabled by default, bearer token required, sensitive header/body redaction, configurable TTL + cleanup via RetentionJob
CLI: cargo-rustapi replay commands (list/show/run/diff/delete)
