Contract

• assert IndexedRandom::choose returns Option while choose_weighted returns Result<&T, WeightError>
• assert an empty slice returns None from choose and Err(InvalidInput) from choose_weighted
• assert all-zero weights return Err(InsufficientNonZero) while negative and NaN weights return Err(InvalidWeight)
• assert IndexedRandom::sample returns distinct references, caps an oversized request at the slice length, and sample_array returns None when the array is too large
• assert IndexedMutRandom::choose_weighted_mut returns a mutable selected item and SliceRandom::shuffle preserves the input elements
• assert Alphanumeric::sample has item type u8, char conversion builds a String, and SampleString builds the requested-length String directly
