Empty Structs

Empty structs are used in Go as a unary value.

example.go

// anonymous empty struct type
empty := struct{}{}

// named empty struct type
type emptyStruct struct{}
empty := emptyStruct{}

The cool thing about empty structs is that they're the smallest possible type in Go: they take up zero bytes of memory.
