# 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>

// DEPRECATED: This file contains unused dead code

// ============================================================================
|
|
// This file documented a runtime registration API for scheduled reducers that
|
|
// was never implemented. The actual C++ scheduled table API uses:
|
|
// - SPACETIMEDB_SCHEDULE(table_name, column_index, reducer_name) macro
|
|
// - ScheduleAt type for scheduled_at columns
|
|
// - See table_with_constraints.h for the real implementation
|
|
// - See modules/module-test-cpp/src/lib.cpp for working examples
|
|
//

// All code below is commented out pending deletion.
