> I am trying to make good use of Generic Interfaces, but can't figure out if its at all possible to delegate calls up the struct inheritance chain. So, something like `call-next`
If I understand you correctly, "define/generic" let you do this. See https://docs.racket-lang.org/reference/struct-generics.html?q=generic#%28form._%28%28lib._racket%2Fgeneric..rkt%29._define%2Fgeneric%29%29 > or even better maybe there's a way to do explicit dispatch? So something like having two structs: If your structs don't inherit from each other, and no configuration of "fallback" or "default" options does what you want, a slightly different approach compared to extracting fish's implementation and reusing it is to use "define/generic" to get the existing "generic" function in your new struct's definition, and have a function convert a marlin to a fish, and then pass that over to the generic function. -- You received this message because you are subscribed to the Google Groups "Racket Users" group.
