Problem
The
Logtrait has memory safety implications in its implementation, but it is not marked asunsafe. The implementation must ensure that the value returned by any of the methods correctly reflects the actual number of bytes written to the buffer. Returning a value greater than the number of bytes written to the buffer will result in undefined behavior, since it will lead to reading uninitialized memory from the buffer.Solution
Add
unsafetoLogtrait to make it explicit that the trait has to be carefully implemented.cc: @d0nutptr
