Poem

In code where tests and docs entwine,
Comments bloom to brightly shine.

The logs shout out, “Hooray!”
With clarity in every line,
The codebase hums, robust, divine.

The documentation now references `bincode::Encode`, which is not a real trait.

`bincode::Encode` is not a valid trait; bincode relies on `serde::Serialize` for encoding. Please update the reference to `serde::Serialize` to prevent confusion.

🔇 Additional comments (5)
wireframe_testing/src/lib.rs (1)

5-7: Excellent documentation enhancement.

The clarification about bincode::Encode trait support improves understanding of the utilities' generic nature whilst keeping the example simple and accessible.

wireframe_testing/src/logging.rs (1)

46-46: Doc test improvement using appropriate log level.

Changing from info! to warn! provides a better example for log assertion testing, as warnings are more commonly captured and verified in test scenarios.

Also applies to: 49-49

tests/push.rs (3)

60-61: Excellent explanatory comment for test context.

The clarification about virtual-time context using tokio::time::pause helps readers understand why time manipulation works effectively in this test environment.


112-113: Clear explanation of shared rate limiting behaviour.

The comment effectively explains why pushes from different priority queues affect each other's rate limits, clarifying the shared token bucket implementation.


149-149: Helpful clarification of burst capacity relationship.

The comment clearly connects the test's burst behaviour to the configured capacity parameter, improving test comprehension.
