NGenXX

A cross-platform framework based on modern C++, supporting biz dev via Lua & JS.

👉 The Rust version(NGenRS) is in works.

Why Rust?

• Guarantee memory safety by the compiler, not the programmer;
• Powerful third-party dependency management tool - Crates, no need to struggle with CMake;
• First-class WASM support, no other toolchain needed(Like Emscripten);
• Complete cross-platform support - FFI, CXX, jni, ojbc2, ohos-rs.
