Result<T, E>, takes two types T and E to work. But this example from the std lib broke my understanding. I mean if they used like
Result<(), _>, I can get it the error type is inferred. But, how does this
Result<()> work? What will be its error type?
io::Result thing is a type alias that is defined like this:
type Result<T> = std::result::Result<T, std::io::Error>;
