What is zyn?

Zyn is a Rust crate for building procedural macros using templates, control flow, and pipes—instead of raw syn parsing and quote chains. It lets you loop over fields with @for, convert cases like snake or pascal inline, and emit diagnostics without extra deps, replacing patchwork scaffolding in proc macro crates. Developers get readable macros that generate clean Rust code, like getters or builders from struct fields.

Why is it gaining traction?

Templates keep expansions concise—no more .iter().map().collect() for fields—while pipes handle 13 case formats (snake, camel, kebab) and custom transforms. It benchmarks faster than darling for attrs and vanilla syn+quote for codegen, with reusable elements for composing derives. The book serves as a procedural macros rust tutorial, and zyn::debug! prints expansions for quick iteration.

Who should use this?

Rust library authors crafting custom derives (e.g., builders, getters) or attributes on structs/enums. Perfect for github procedural macro examples or replacing hand-rolled parsing in serialization or validation crates. Skip if you need C++-style macros or Unity procedural generation.

Verdict

Worth adding to new proc macro projects—excellent docs and benches outweigh 13 stars and 1.0% credibility score. Early v0.3 means test thoroughly, but it already simplifies Rust procedural macro development over syn stacks.
