Warning

Review limit reached

@burakssen, you've reached your PR review limit, so we couldn't start this review.

Limit details: You’ve used all 1 included review currently available under your plan.

You've used all free OSS reviews for now. Wait for the free limit to reset to keep reviewing this public repository.

How can I continue?

After more reviews become available, a review can be triggered using the @coderabbitai review command as a PR comment. Alternatively, push new commits to this PR.

To avoid repeated limits, reduce automatic review volume by pausing incremental auto-reviews earlier, using label-based review opt-in, excluding WIP or generated PR titles, or requesting reviews manually when the PR is ready. If your team needs uninterrupted high-volume reviews, an organization admin can enable usage-based reviews.

How do review limits work?

CodeRabbit enforces per-developer PR review limits for each organization. Most developers receive the normal plan review availability.

For paid Pro and Pro+ PR reviews, CodeRabbit uses adaptive limits for sustained high-volume activity. When a developer's recent PR review activity reaches the 95th percentile or higher among CodeRabbit users, additional reviews become available more gradually as earlier reviews age out of the rolling window.

Please refer docs for additional details.

📝 Walkthrough

Walkthrough

The package now requires Zig 0.17.0-dev.1552+79dc16a0e. Internal NIL construction, benchmark buffers, benchmark separators, and test fixtures use updated Zig initialization syntax. Exported declarations and behavior remain unchanged.

Changes

Zig compatibility updates

Layer / File(s)	Summary
Compiler baseline and NIL syntax build.zig.zon, src/msgpack.zig, src/test.zig	The minimum Zig version is updated. NIL payload construction now uses {} instead of void{}.
Benchmark initialization and separators src/bench.zig	Benchmark buffers use @splat, medium strings use concatenated base strings, and output sections reuse precomputed separators.
Test fixture initialization src/test.zig	String boundary and PackerIO tests use fixed-size byte arrays with @splat or array references.

Estimated code review effort: 2 (Simple) | ~10 minutes

Merge Risk: 🔴 Critical · up to 5d2a1

The Zig 0.17 compatibility patch still contains a void{} literal that the target compiler no longer supports, so the library may fail to compile for Zig 0.17 users. This is a merge-blocking issue until the literal is replaced.

Can you do some compatibility work? I don't want to drop support for 0.16.
