# Description of Changes This adds C++ server bindings (/crate/bindings-cpp) to allow writing C++ 20 modules. - Emscripten WASM build system integration with CMake - Macro-based code generation (SPACETIMEDB_TABLE, SPACETIMEDB_REDUCER, etc) - All SpacetimeDB types supported (primitives, Timestamp, Identity, Uuid, etc) - Product types via SPACETIMEDB_STRUCT - Sum types via SPACETIMEDB_ENUM - Constraints marked with FIELD* macros # API and ABI breaking changes None # Expected complexity level and risk 2 - Doesn't heavily impact any other areas but is complex macro C++ structure to support a similar developer experience, did have a small impact on init command # Testing - [x] modules/module-test-cpp - heavily tested every reducer - [x] modules/benchmarks-cpp - tested through the standalone (~6x faster than C#, ~6x slower than Rust) - [x] modules/sdk-test-cpp - [x] modules/sdk-test-procedure-cpp - [x] modules/sdk-test-view-cpp - [x] Wrote several test modules myself - [x] Quickstart smoketest [Currently in progress] - [ ] Write Blackholio C++ server module --------- Signed-off-by: Jason Larabie <jason@clockworklabs.io> Co-authored-by: clockwork-labs-bot <clockwork-labs-bot@users.noreply.github.com> Co-authored-by: Ryan <r.ekhoff@clockworklabs.io> Co-authored-by: John Detter <4099508+jdetter@users.noreply.github.com>

# SDK Test Procedure C++
|
|
|
|
This module tests the procedure functionality in the SpacetimeDB C++ bindings.
|
|
|
|
## Tests Included
|
|
|
|
- **return_primitive**: Procedure returning primitive type (u32)
|
|
- **return_struct**: Procedure returning custom struct
|
|
- **return_enum_a/return_enum_b**: Procedures returning enum variants
|
|
- **will_panic**: Procedure that panics (for error testing)
|
|
|
|
## Tests Excluded (Part 2+)
|
|
|
|
The following Rust tests are excluded as they require features not yet implemented:
|
|
- HTTP requests (`read_my_schema`, `invalid_request`)
|
|
- Transactions (`insert_with_tx_commit`, `insert_with_tx_rollback`)
|
|
- Scheduled procedures (`schedule_proc`, `scheduled_proc`)
|
|
|
|
## Building
|
|
|
|
```bash
|
|
.\compile.bat
|
|
```
|
|
|
|
This will generate `lib.wasm` in the build directory.
