Issue

Panics due to negative results caused by world.next_right - 5

riverraidrust/src/main.rs

Line 205 in f98ff4d

world.next_right = rng.gen_range(world.next_right-5..world.next_right+5);

Suggestion

using saturating_sub() to avoid panicking by negative results
using max() as an easy way to set boundaries

• saturating_sub(5) results 0 >=
• world.next_left + 3 results 3 >=
• Therefore max() results 3 >=

world.next_right = rng.gen_range(

max(world.next_right.saturating_sub(5), world.next_left + 3) .. world.next_right + 5

);
