Zig project adopts flat file structure and minimal tooling after Rust developer comparison
A Rust developer reimplemented a JSONPath library in Zig and documented differences in tooling and project structure
Zig’s minimalism challenges assumptions about tooling and file organization carried over from Rust. The experience highlights trade-offs between IDE reliance and CLI workflows, as well as the scalability of flat project structures for small to medium projects. Engineers evaluating Zig may need to adjust expectations around tooling maturity and project layout conventions

THE READ
What the cluster adds up to.
A Rust developer reimplemented a JSONPath library in Zig to compare the languages firsthand. The project revealed practical differences in tooling and project structure that aren’t immediately apparent from language specifications. While Rust encourages deep folder hierarchies and IDE integration, Zig’s minimalism pushed the developer toward a flatter file structure and command-line workflows. This contrast suggests Zig may be better suited for engineers comfortable with lightweight tooling or those working on smaller-scale projects
The lack of robust IDE support in Zig was initially a hurdle but ultimately led to a simpler development environment. The developer adopted a terminal-based setup using helix, alacritty, and zellij instead of relying on JetBrains IDEs. Zig’s build system, configured via build.zig, provided straightforward commands for testing and compliance checks. This shift demonstrates that Zig’s tooling, while less mature than Rust’s, can still support efficient workflows for engineers willing to adapt to command-line interfaces
Zig’s approach to file organization differs significantly from Rust’s. The developer found that Zig’s flat structure reduced the need for deep folder hierarchies, even for a project of moderate complexity. While Rust projects often split code into many small files and nested directories, Zig encouraged keeping related code in single files or adjacent files. This forced a reevaluation of whether folder structures were truly necessary or just habitual. The experience suggests Zig may scale differently than Rust, with larger projects potentially requiring different organizational strategies
The comparison highlights how language design influences engineering habits. Rust’s functional leanings and expressive type system contrast with Zig’s simplicity and explicitness. The developer noted that Rust habits, like early folder structuring, didn’t always translate well to Zig. This underscores that adopting Zig may require unlearning some Rust conventions, particularly around project organization and tooling. Engineers considering Zig should expect to rethink workflows rather than assuming direct carryover from other languages
