Function Signatures

[David Richard]

Hi Folks,

I'm attempting to wrap your library in an additional abstraction library of my own design. The intention is to create convenience functions to create REST services. This may be more of a Go question than anything, but I have tracked the problem down to your validation code when adding handlers (isValidHandler).

Your functions require the following signature:

func YourFunctionName(rw web.ResponseWriter, req *web.Request)

So that all of my libraries that create handlers aren't required to include your library as well as my new one, I have created a set of types to accommodate your signatures:

type PathHandler func(rw WebWriter, req *WebRequest)
type WebWriter web.ResponseWriter
type WebRequest web.Request

In this manner, my functions can adhere to this type PathHandler

func Read(rw WebWriter, req *WebRequest) {
    ...
}

func GenerateReadEndpoint() PathHandler {
    return Read
}

The code panics when trying to add the handler via router.Get() etc., as the isValidHandler function rejects the types I have created.

Is there any way to accomplish this, or do you have a function type that I may have missed that I can use to abstract your library?

Thanks.
