Summary

`impl Random` on arrays can lead to dropping uninitialized memory

Details

Affected versions of this crate had a panic safety issue to drop partially uninitialized array of T upon panic in a user provided function T::random(). Dropping uninitialized T can potentially cause memory corruption or undefined behavior.

The flaw was corrected in commit 565d508 by using MaybeUninit<T> to avoid possible dropping of uninitialized memory upon panic.
