SIMD-accelerated, zero allocation CSV library in Zig
Field iterator + zero alloc forces explicit ownership; SIMD scanning is clever but niche.

Zero-allocation and SIMD-accelerated CSV iterator in Zig
by peymo·Feb 23, 2026·2 points·0 comments
Post Description
I needed a CSV library in Zig and I hand rolled one. Then I decided to come back to it and make it avoid allocations entirely and then went down a rabbit hole of performance tuning and learned a ton in the process.
This is the result. I also added a benchmarking library and a blog post that explains the implementation details. All are available in the repo page.
I presented this in a local Zig meetup and it landed well so I figured I'll post it here as well.
