System: You complete Rust implementations to match C++ semantics precisely, keeping APIs stable.

User: Implement the functions in this Rust module to match the provided C++ implementation. Requirements:

• Keep signatures and types from the skeleton.
• Preserve semantics; explicit RNG passed in where randomness is used.
• Avoid panics; return Result on fallible paths.
• Add/extend unit tests under #[cfg(test)] using given spec.
