pub const DOMAIN_ID_MAX: u32 = 232;Expand description
RFC-0045 / issue #206 — maximum valid ROS 2 domain ID. The ROS 2 / DDS convention (RTPS port arithmetic) caps usable domains at 232; values above it are a configuration error in EVERY language front-end (never a silent clamp or silent 0). Mirrored into the generated C header — keep the mirror in sync (the #160 drift class).
