Re: [go-nuts] Re: When do you recommend not using composition?

Thank you, Ian. It indeed makes documentation easier to read in this case. Unless the interface to be embedded is sufficiently self-documenting, as is the case with `heap.Interface` embedding `sort.Interface`, I will stick to listing the method[s] directly. https://cs.opensource.google/go/go/+/

I understand that interface does not provide the implementation. Perhaps my question was not clear. Let me try with the code snippets. This is how http.ResponseWriter is written: type http.ResponseWriter interface { ... Write([]byte) (int, error) ... } But it could have also been wri

[go-nuts] Re: When do you recommend not using composition?

I would recommend reading up on how to implement Go interfaces. The only requirement required to satisfy the io.Writer interface is a method Write([]byte)(int,error). If this method is present, Go can then interpret your struct as a io.Writer. By itself, io.Writer provides no functionality only

[go-nuts] When do you recommend not using composition?

Is there a reason why `http.ResponseWriter` does not include io.Writer directly and instead has the `Write([]byte) (int, error)` method? Why did you choose to do it this way? I can see that it adds a dependency on the io package. Was that the concern? And more generally, when would you recommen
