Zngur: Simplified Rust/C++ Integration
Talkat RustConf 2026 · on Wednesday, 2026-09-09· at 11:05· Room 510bd | Palais des Congrès de Montréal, Palais des Congrès de Montréal·
summary
Zingar generates C++ headers, C++ sources and generated Rust from a single ZNG file, letting C++ call arbitrary Rust crates with direct, Rust-like APIs; Rust calling C++ requires C++ adapter implementations and three representation choices including CPP heap allocated for compatibility. Adobe reports successful integration into flagship apps for safety‑critical parsers and shows the benefit of Cargo plus normal C++ toolchains (generate, cargo build, clang link). Real example swaps libpng (about 75 CVEs) for a Rust PNG crate with no unsafe code.
