Tracking issue for everything we want to have for a first version of an officially supported C++ SDK.

General guideline:

• Feature complete: Log everything that the new object oriented Python API can log
• First class: Once this ticket is closed we treat it just like our Rust and Python SDK, the same principles for CI, docs, quality etc. apply
• basic distributability - we have an installation guide but it doesn't need to be smooth at this point
• works on Linux & Mac, Windows optional at this point

Must have:

• feature complete logging
  • Archetypes migration tracking issue #2795
  • C++: Tensor migration to archetypes #3380
  • Some C++ code-examples seg-fault #3864
  • C++: Failure to serialize rotations (code-examples/transform3d_simple) #3865
• Docs & Samples
  • Implement missing code-examples for C++ #3751
  • Port "getting started" example code to C++ #3752
  • C++ Getting Started and tutorial documentation #3753
  • Add C++ to in-viewer quick-start guide #3870
• Code & library quality
  • [C/C++] Introduce unified error handling #2917
  • improve header quality - Don't leak arrow headers into Rerun C++ API headers #2873
  • Build with warnings as errors on CI for C++ #2903
  • Exclude mock archetypes/datatypes/components from release artifacts #2537
• C++ implement logging with timestamps #3394
• log_clear
• C++ component splatting support #3040
• Turn on "strict mode" in code-examples and tests (throw on errors instead of logging) #3867
• C++ make it easy to turn off logging #3754
• Clean up C++ naming in samples and SDK #3755
• Add C++ example with logging data from Eigen/OpenCV #3758
• Provide CMake setup for using the C++ sdk with pre-built rerun_c #3759

Stretch-goals

• C++: Add standalone user-defined archetype+component example #3139
• check on distribution size - Make rerun_c smaller #2905
• Add spawn-like functionality to C++ and Rust #3757
• [C++] List out supported compilers, language version etc. in docs #3975
• C++ Windows/MSVC full support + testing on CI #3756
• zero copy logging - C++ Component arrays (in Archetypes and log_components) need to be optional non-owning (& mappable) #3050

Future (i.e. excluded from this release)

• easy setup
  • no manual libarrow install etc.
  • support one or more C++ package manager
• C++14 support (requiring C++17 so far)
• [C++] Out-of-the-box support for Eigen & OpenCV types #3977
• Run just cpp-test on CI
  * Use pixi for all cpp test invocations on CI #3921
  * note that we already run all tests, so this isn't critical at all
• Explore possibility to bundle libarrow so users don't need to install it #3976
• Sanity-check that the C header version and rerun_c library version is the same #3868
• C++ API Docs webpage #3974
