"safe" and "unsafe" in rust are well defined, but in my opinion it's very confusing and I wish they used different terms. In rust, unsafe means accessing memory that's already freed or unallocated or things like that. You can look up the definition for the full definition. I think the comment you replied to mistakenly used the term "unsafe" (that's part of the reason I dislike the term; it can mean multiple things). In rust context though, it isn't unsafe to index an array that's out of bounds. I.e. if argc=10 and you call argv[99], that will crash your program but isn't considered "unsafe".
