🧹 Nitpick comments (3)
src/lib.rs (2)
426-427: Ensure error type is properly handled downstream.Changing the
installmethod to returnResult<(), SetRecorderError<Self>>captures the specific exporter type in the error. Verify all call sites handle this specialized error gracefully (e.g., producing meaningful messages or logs).
454-456: Consider the data volume in this test loop.Recording metrics continuously at short intervals can produce a large volume of data. If the test’s intention is stress testing, this is fine. Otherwise, you could reduce frequency or limit iteration to prevent excessive storage usage.
src/recorder.rs (1)
184-184: Consider utilizing the metadata parameter.The
_metadataparameter is currently unused (indicated by the underscore prefix). Consider using this metadata for enhanced logging or database storage as suggested by the comment on line 183.- fn register_counter(&self, key: &Key, _metadata: &Metadata) -> Counter { + fn register_counter(&self, key: &Key, metadata: &Metadata) -> Counter { let sender = self.sender.clone(); + // Store metadata in SQLite for informational usage + if let Err(e) = self.sender.try_send(Event::StoreMetadata(key.clone(), metadata.clone())) { + error!("Error sending metadata: {:?}", e); + }Also applies to: 200-200, 216-216

8-8: Adoptedtracingmacros successfully.Switching from
logtotracingaligns with the PR's objective to migrate to the new logging framework. This line is correct and consistent with the rest of your changes.examples/import_csv.rs (2)
2-2: Importedtracing_subscriberfor logging.Pulling in
tracing_subscriberis consistent with the transition away from older logging frameworks.
5-11: Configured environment-based filter and formatted logging.The fallback to
infoif the environment variable is undefined is a sensible default. This setup ensures logs are clearly formatted and adjustable based on runtime needs.examples/simple.rs (3)
4-4: Switched totracing_subscriberimport.This addition mirrors the project's overall move away from
pretty_env_logger.
18-25: Initialized structured logging.Combining the filter and formatting layers provides a clean, extensible logging approach. No issues observed here.
34-36: Updated counters and gauges with method-based API.Using
.increment()and.set()is aligned with the new metrics API. This change ensures consistency across the codebase.examples/large-file.rs (3)
4-5: LGTM! Imports align with the PR objectives.The imports correctly include the necessary
tracing_subscribermodules for the new logging setup.
20-27: LGTM! Logging setup follows best practices.The logging configuration is well-structured:
- Uses environment-based filter with fallback to "info" level
- Properly layers the formatting and filtering components
38-44: LGTM! Metrics recording updated to use modern method chaining.The changes consistently use
.set()for gauges and.increment()for counters, improving code readability.src/recorder.rs (1)
3-10: LGTM! Import organization improved.The imports are well-organized and include the necessary
Metadatatype for the updated method signatures.Cargo.toml (3)
3-3: LGTM! Version bump follows semver.The version increase to 0.5.0 is appropriate for the new features and dependency updates.
26-26: LGTM! Logging transition complete.The replacement of
pretty_env_loggerwithtracing-subscriberaligns with the PR objectives.
