Zig with OCaml: C Stubs, Bigarray Interop, Custom Blocks, and Callback Boundaries

A practical two-hour session on Zig with OCaml, focused on C Stubs, Bigarray Interop, Custom Blocks, and Callback Boundaries. The session treats Zig as a native component exposed through C-compatible boundaries, with attention to exported symbols, allocators, packaging, host-runtime tests, and failure handling.

Audience: entry-level and intermediate developers who want a practical engineering session, not a language tour.

Outcomes:

• Explain the practical boundaries of Zig with OCaml
• Apply C Stubs in a small working example
• Apply Bigarray Interop in a small working example
• Apply Custom Blocks in a small working example

Format: two hours with a short framing walkthrough, a concrete example, discussion of tradeoffs, and a closing checklist for practice.
