# Module Structure Fixes Completed
## Issues Fixed:
1. **Fixed duplicate `kernel_function` macro export**
- Removed duplicate macro definition from `error.rs`
- Kept the proper implementation in `runtime/kernel.rs`
- Fixed incorrect re-export attempts in `lib.rs`
2. **Fixed transpiler module structure**
- Added missing `ast` module to `transpiler/mod.rs`
3. **Fixed backend_trait module exports**
- Added `BackendTrait` export in `backend/mod.rs`
- Added backward compatibility alias `Backend` for `BackendTrait`
- Updated `BackendCapabilities` struct to include all required fields
4. **Created missing unified_memory module**
- Implemented `UnifiedMemory` struct with proper allocation/deallocation
- Added safety implementations for Send/Sync
- Included helper functions and tests
5. **Fixed profiling module CudaError type**
- Changed all references from `CudaError` to `CudaRustError`
- Updated all IO error handling to properly convert to `CudaRustError`
- Fixed export functions in all profiling submodules
6. **Fixed wasm_runtime module**
- Updated to implement the correct `BackendTrait` interface
- Added async trait support
- Implemented all required trait methods
- Fixed `BackendCapabilities` initialization
7. **Added missing error macros**
- Added `memory_error!` macro to `error.rs`
## Module Structure Now:
- All imports should resolve correctly
- No duplicate macro exports
- All trait implementations match their definitions
- All error types are consistent
## Remaining Issues (not module-related):
- Type mismatches in AST structures (parser vs transpiler AST types)
- Missing method implementations in various structs
- These are implementation issues, not module organization issues
