This is crucial for real-time systems (, ) wherein besides determinism and performance, quality and security also benefit significantly from using, . Note. This updated version includes the changes in data type nesting and naming, for example: An earlier type definition might look like this: module std_msgs { module msg { struct Bool { boolean data; }; };}; module std_msgs { module msg { module dds_ { struct Bool_ { boolean data; }; }; };}; Note the added layer of nesting under "dds_", and the trailing underscore on the struct name "Bool_".This matches the types that are generated in the ROS2 build system. Connect and share knowledge within a single location that is structured and easy to search.
