Summary by Sourcery

Replace the macro-generated drive_with_frame helper with an explicit async function that delegates to drive_with_frame_with_capacity using the default buffer capacity.

New Features:

  • Expose drive_with_frame as an async function returning the processed bytes

Enhancements:

  • Remove the macro-based drive_with_frame definition in favor of a direct async helper
  • Forward the new drive_with_frame to drive_with_frame_with_capacity using DEFAULT_CAPACITY

Summary by CodeRabbit

  • Documentation

    • Improved documentation for the drive_with_frame function, including a detailed section on error handling.
  • Refactor

    • Replaced a macro-generated function with an explicitly defined async function, maintaining the same behaviour and signature.

Walkthrough

Replaced the macro-generated async function drive_with_frame in wireframe_testing/src/helpers.rs with an explicit async function. The new function declares generics and trait bounds explicitly, calls drive_with_frame_with_capacity with a default capacity, and includes expanded documentation. No logic or control flow changes were introduced.

Changes

Cohort / File(s) Change Summary

wireframe_testing/src/helpers.rs
Removed macro-generated drive_with_frame. Added explicit async function with generics S, C, E and trait bounds, calling drive_with_frame_with_capacity with default capacity. Expanded function documentation with error details. No behavioural changes.

Poem

Wave goodbye to macros, say hello to clear code,
Async functions now stand in explicit mode.
Generics in place, with bounds that align,
Documentation shines, errors defined fine.
Helpers refreshed, neat and concise,
Wireframe’s journey just got more precise! 🚀✨

153-183: LGTM! Excellent improvement in code clarity.

The replacement of the macro-generated function with an explicit async implementation significantly improves code readability and maintainability. The function signature, generic constraints, and documentation are all properly defined, and the # Errors section has been correctly added as requested in the previous review.

Chat

There are 3 ways to chat with CodeRabbit:

  • Review comments: Directly reply to a review comment made by CodeRabbit. Example:
    • I pushed a fix in commit <commit_id>, please review it.
    • Explain this complex logic.
    • Open a follow-up GitHub issue for this discussion.
  • Files and specific lines of code (under the "Files changed" tab): Tag @coderabbitai in a new review comment at the desired location with your query. Examples:
    • @coderabbitai explain this code block.
  • PR comments: Tag @coderabbitai in a new PR comment to ask questions about the PR branch. For the best results, please provide a very specific query, as very limited context is provided in this mode. Examples:

📄 CodeRabbit Inference Engine (AGENTS.md)

**/*.rs: Function documentation must include clear examples demonstrating the usage and outcome of the function. Test documentation should omit examples where the example serves only to reiterate the test logic.
No single code file may be longer than 400 lines. Long switch statements or dispatch tables should be broken up by feature and constituents colocated with targets. Large blocks of test data should be moved to external data files.
Clippy warnings MUST be disallowed.
Fix any warnings emitted during tests in the code itself rather than silencing them.
Where a function is too long, extract meaningfully named helper functions adhering to separation of concerns and CQRS.
Where a function has too many parameters, group related parameters in meaningfully named structs.
Where a function is returning a large error consider using Arc to reduce the amount of data returned.
Write unit and behavioural tests for new functionality. Run both before and after making any change.
Every module must begin with a module level (//! ) comment explaining the module's purpose and utility.
Document public APIs using Rustdoc comments (///) so documentation can be generated with cargo doc.
Prefer immutable data and avoid unnecessary mut bindings.
Handle errors with the Result type instead of panicking where feasible.
Avoid unsafe code unless absolutely necessary and document any usage clearly.
Place function attributes after doc comments.
Do not use return in single-line functions.
Use predicate functions for conditional criteria with more than two branches.
Lints must not be silenced except as a last resort.
Lint rule suppressions must be tightly scoped and include a clear reason.
Prefer expect over allow.
Prefer .expect() over .unwrap().
Use concat!() to combine long string literals rather than escaping newlines with a backslash.
Prefer semantic error enums. Derive std::error::Error (via the thiserror crate) for any condition the caller might inspect, retry, or map to an HTTP status....

146-156: Good replacement of the macro with an explicit async function

Explicit code improves readability and makes trait bounds visible at the call-site without relying on macro expansion. Implementation correctly delegates to the capacity-aware variant and preserves behaviour.
