For slices the access is handled inside of the compiler: https://github.com/rust-lang/rust/blob/235a4c083eb2a2bfe8779d211c3232f39396de00/library/core/src/slice/

I had Vec in mind but regardless nothing forces you to use the bounds-checked variant vs one that returns option<t>. And if you really are sure the bounds hold you can always use the assume crate or just unwrap_unchecked explicitly.
