Safe Lock-free Primitives with iceoryx2's ByteAtomic
iceoryx2 introduces ByteAtomic, a byte-wise atomic wrapper that safely implements lock-free primitives like sequence locks by performing atomic memory operations at the byte level. This solves a critical problem in Rust and C++ where copying non-atomic shared data during concurrent access triggers undefined behavior, even if the data race is subsequently detected. ByteAtomic enables safe lock-free constructs for safety-critical systems without relying on proposed standard library features like atomic memcpy.
