根因分析

调用了标记为 'unsafe' 的函数，但没有将其包裹在 'unsafe {}' 块中。

English

Calling a function marked as 'unsafe' without wrapping it in an 'unsafe {}' block.

解决方案

  1. Wrap the unsafe call in an 'unsafe { ... }' block. Example: 'unsafe { std::ptr::read(ptr); }'
  2. If the function has a safe wrapper, use that instead. E.g., use 'std::slice::from_raw_parts' via safe abstractions.

无效尝试

常见但无效的做法:

  1. 70% 失败

    Adding 'unsafe' to the function signature instead of wrapping the call in a block — this changes the function's contract but doesn't fix the call site.

  2. 90% 失败

    Using '#[allow(unsafe_code)]' lint suppression — this only silences the warning, not the error, and doesn't make the code compile.
