Easily Leverage Native Functions with Project Panama from Java

on YouTube ↗29m

" summary

Shows how to call native C/Swift/Rust libraries directly from Java using JEP-419 (Foreign Function & Memory API) and the system linker, allocating MemorySegment arenas and invoking native symbols via generated MethodHandles. Demonstrates using jextract to generate bindings for libs like libsodium and a Rust blake3 implementation, enabling native access flags and incubator modules in JDK 18/19 previews, and argues this Panama approach is faster and simpler than JNI/JNA while using native memory scopes that auto-free.
