# VDE-011: write_stl / write_stl_ascii 返回 void
|
|
|
|
|
|
|
|
|
|
|
|
## 问题描述
|
|
|
|
|
|
|
|
|
|
|
|
write_stl() 和 write_stl_ascii() 的返回类型为 void，调用者无法判断写入是否成功。规范的做法是返回 bool 或抛出异常（如 read_stl 所做的）。函数签名：
|
|
|
|
|
|
|
|
|
|
|
|
```cpp
|
|
|
|
|
|
void write_stl(const std::string& filepath, const std::vector<StlTriangle>& tris);
|
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
|
|
## 影响文件
|
|
|
|
|
|
|
|
|
|
|
|
- include/vde/foundation/io_stl.h
|
|
|
|
|
|
|
|
|
|
|
|
## ViewDesign 侧 Workaround
|
|
|
|
|
|
|
|
|
|
|
|
调用后假定成功，返回 true。
|
|
|
|
|
|
|
|
|
|
|
|
## 建议修复方向
|
|
|
|
|
|
|
|
|
|
|
|
1. 改为返回 bool（或 std::expected<void, Error> 在 C++23）
|
|
|
|
|
|
2. 像 read_stl 一样在失败时抛出 std::runtime_error
|
|
|
|
|
|
3. 至少应在文档中说明该函数如何报告写入失败
