🗂️ Phase 9.75D: Remove duplicate traits.rs file - complete trait consolidation
## Summary
- Removed unused duplicate file: src/boxes/traits.rs (88 lines)
- Kept main trait definition file: src/box_trait.rs (904 lines, 60+ files using it)
- Completed trait system consolidation
## Analysis Results
- ❌ src/boxes/traits.rs: 88 lines, 0 files using it, missing share_box() method
- ✅ src/box_trait.rs: 904 lines, 60+ files using it, complete trait implementation
## Changes Made
- Deleted: src/boxes/traits.rs (outdated, incomplete, unused)
- Preserved: src/box_trait.rs (current, complete, widely used)
## Verification
- ✅ `cargo check` passes successfully (no errors, only warnings)
- ✅ No build dependencies broken
- ✅ All Box trait implementations remain functional
- ✅ Unified trait system with single source of truth
## Result
- Single authoritative trait definition file
- Eliminated confusion from duplicate implementations
- Cleaner codebase architecture
- Ready for Phase 9.75D VM/WASM backend development

## 🛠️ **実装戦略**
|
|
|
|
|
|
|
|
|
|
### Phase 1: BoxCall基本実装 (1週間)
|
|
|
|
|
```rust
|
|
|
|
|
// 目標: 基本的なNyashプログラムがWASMで動作
|
|
|
|
|
impl WasmCodegen {
|
|
|
|
|
fn generate_box_call(&mut self, dst: Option<ValueId>, box_val: ValueId,
|
|
|
|
|
method: &str, args: Vec<ValueId>) -> Result<(), WasmError> {
|
|
|
|
|
match method {
|
|
|
|
|
"toString" => self.generate_to_string_call(dst, box_val),
|
|
|
|
|
"equals" => self.generate_equals_call(dst, box_val, args),
|
|
|
|
|
"length" => self.generate_length_call(dst, box_val),
|
|
|
|
|
// ... 基本メソッド追加
|
|
|
|
|
_ => Err(WasmError::UnsupportedInstruction(format!("Unknown method: {}", method)))
|
|
|
|
|
}
|
|
|
|
|
}
|
|
|
|
|
}
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
### Phase 2: ExternCall統合 (2週間)
|
|
|
|
|
```rust
|
|
|
|
|
// 目標: ブラウザーとの連携動作
|
|
|
|
|
impl RuntimeImports {
|
|
|
|
|
fn register_browser_apis(&mut self) {
|
|
|
|
|
self.register("console_log", console_log_impl);
|
|
|
|
|
self.register("canvas_fillRect", canvas_fill_rect_impl);
|
|
|
|
|
// ... ブラウザーAPI追加
|
|
|
|
|
}
|
|
|
|
|
}
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
### Phase 3: 最適化・高級機能 (1ヶ月)
|
|
|
|
|
- 制御フロー最適化
|
|
|
|
|
- メモリ管理改善
|
|
|
|
|
- パフォーマンス向上

🗂️ Phase 9.75D: Remove duplicate traits.rs file - complete trait consolidation
## Summary
- Removed unused duplicate file: src/boxes/traits.rs (88 lines)
- Kept main trait definition file: src/box_trait.rs (904 lines, 60+ files using it)
- Completed trait system consolidation
## Analysis Results
- ❌ src/boxes/traits.rs: 88 lines, 0 files using it, missing share_box() method
- ✅ src/box_trait.rs: 904 lines, 60+ files using it, complete trait implementation
## Changes Made
- Deleted: src/boxes/traits.rs (outdated, incomplete, unused)
- Preserved: src/box_trait.rs (current, complete, widely used)
## Verification
- ✅ `cargo check` passes successfully (no errors, only warnings)
- ✅ No build dependencies broken
- ✅ All Box trait implementations remain functional
- ✅ Unified trait system with single source of truth
## Result
- Single authoritative trait definition file
- Eliminated confusion from duplicate implementations
- Cleaner codebase architecture
- Ready for Phase 9.75D VM/WASM backend development
