Rust Libraries for Clojure and Scala: Java 26 FFM API, `jextract`, MemorySegments, and JVM Data Boundaries

A practical two-hour session on Rust Libraries for Clojure and Scala, focused on Java 26 FFM API, jextract, MemorySegments, and JVM Data Boundaries. The session treats Rust as a native component exposed through C-compatible boundaries, with attention to packaging, ownership, 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 Rust Libraries for Clojure and Scala
• Apply Java 26 FFM API in a small working example
• Apply jextract in a small working example
• Apply MemorySegments 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.
