C++ SDK

transit-client-cpp and transit-station-cpp separate raw signed operations from Station's typed handlers, state and durable calls. Shared Zig owns protocol and framework semantics; these packages own language types, codecs, scheduling and packaging.

Installation

Use C++17 callers and the pinned Zig compiler on Linux x86_64. Build all artifacts from the same checkout using the source build instructions. Native artifacts require that build's Nix runtime closure. Other platforms and portable native distributions are not supplied.

Extract the C++, C SDK and matching native archives into one prefix. Use its lib/pkgconfig directory with the transit-client-cpp or transit-station-cpp pkg-config package. C++ wrappers link the installed C SDK; they do not duplicate native protocol logic.

Include transit/client.hpp or transit/station.hpp. The APIs provide typed values and move-only owners. RAII controls local lifetime; destruction does not undo accepted requests. Use explicit saved-command recovery for unknown outcomes. Headers, C SDK libraries and native artifacts must share the current definition.

Select credentials and the native profile explicitly. A locally compatible library does not establish current server capabilities or authorization. Retain the original canonical request after an unknown outcome; closing a handle or cancelling a host task does not undo accepted work.
