This can be This is a bit nitpicking from my side, but usually when referring to the name of a function, I would suggest adding the parentheses, i.e. "bytes_add_one()". In this way, it's more clear that it's a function (instead of a variable or something else). > simplified to `Result` as default type parameters are unit `()` and > `Error` types.
