📝 Walkthrough

Walkthrough

The package now requires Zig 0.16.0. 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 changes from 0.14.0 to 0.16.0. 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: 🟠 High · up to 9d81d

The Zig 0.17.0 migration still retains obsolete void{} syntax in src/msgpack.zig, creating a concrete risk that the project will not compile for the supported version; this should be fixed before merging.

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

Sure, I'll try to complete until tomorrow.

Hi, I just checked, and all the code works with both Zig 0.16.0 and 0.17-dev. Should I just update the minimum_zig_version in build.zig.zon? It was previously set to 0.14.0, so should I change it to 0.16.0 or leave it at 0.14.0?

[jinzhongjia]

0.16.0

I've been quite busy with work lately, so I might merge this PR later.
