I'm learning Rust and I'm very new so I was learning about the sort of "environment" to Rust (Cargo, etc.) and I have been struggling so much with the concept of rust crates. I've gone to so many websites and YouTube videos and AI but I just cannot grasp what they are. Every time I get "the smallest amount of code the compiler considers at the same time" or "the smallest unit of rust code" or something like that as the answer but I just don't know what they are. I understand that there are binaries and libraries, my question is more like the "visual" side of it, like if you look at a rust program how do you identify where the crates are, like what is part of each crate. I'm sort of looking for where a crate ends and another crate begins. Idrk, sorry if this is a bad question.
