Boost Your Intra-Process Communication Programs With C++20 & Contract-Concept-Implementation Pattern
summary
Claims a concrete pattern: Concept-Constraint-Implementation (CCI) pattern plus C++20 concepts wrap low-level sdbus IPC calls into types that enforce lifetimes, service-name formats, and automatic DBus signatures. Example reworks an image channel-extraction service (file path, save path, channel) into constrained types, removes manual signature strings, and catches many errors at compile time. A microbenchmark compiles a constexpr path into two assembly instructions. Pattern reduces runtime faults but admits some checks must remain at runtime and is not universally appropriate.
