Either the code generator should be easy to enhance or it should have a side car data field - anything else is hard to rationalize as even rudimentary design. 

Re: [go-nuts] Adding methods to non local types that use more state than available in the non local type

Now that I think about it again - I guess your suggestion could work for my case with some caveats: 1. There can be contention on the map - but as you point out there is sync.Map as well 2. The state should be removed from the map but that can also be arranged by deferring a delete operation 3. If

Re: [go-nuts] Adding methods to non local types that use more state than available in the non local type

Forgive me if this off base, as I'm still a little fuzzy on the exact constraints of you problem... but, as stated, if you want to associate additional optional behavior and state with any given response that is constrained to the generated, just use the responses's pointer (to its struct) (if lo

Re: [go-nuts] Adding methods to non local types that use more state than available in the non local type

seems a very common assumption I would have guessed it is due to compatibility with C but https://pkg.go.dev/cmd/cgo#hdr-C_references_to_Go explicitly states: *Go struct types are not supported; use a C struct type. * So it may be completely at the decision of the implementer. The caveats in http

Hello all and thanx for the answers. Here I provide more information: @Robert Engels | Just have the parameters be interfaces and do reflection/type casting. I sadly cannot do this (at least right away). That is why I asked for help. I cannot guarantee the parameters are interfaces - they are what

Re: [go-nuts] Adding methods to non local types that use more state than available in the non local type

If you look at the example given the function accepts the base type and then tries to call the function needing the extended type - pretty sure you can’t do this with embedding as the type is erased when the outer function is called. You need an interface afaik. On May 11, 2025, at 8:43 PM, Jason E

Re: [go-nuts] Adding methods to non local types that use more state than available in the non local type

I think you have just misunderstood how to embed types in Go, because you say *> // Declare a new type that embeds the generated.Response> type EnrichedResponse generated.Response* and this is not type embedding, it is just a type definition, giving a new name and new type for the existing st

[go-nuts] Adding methods to non local types that use more state than available in the non local type

Hi all, I need some guidance whether what I want to do is somehow possible in Go. I've already searched answers for two days. My problem boils down to how to sneak more in a type without changing the type. Lets say I have to implement the following method: *func (s *server) Get(ctx context.

[go-nuts] Re: net/icmp: Echo.ID and Echo.Seq are defined as int, but Marshal converts them to uint16

Hi Yuen Sun, Your question is a fine one, but better directed to the Go development team than to general users of Go. If its going to be fixed, it will need issue anyway, so I suggest simply filing an issue and/or asking on golang-dev. https://github.com/golang/go/issues https://groups.google.com

Of that I’m not sure. It is based on deep knowledge of how these things are built from the hardware to the kernel to network protocols to the service layers. It broadly falls under performance tuning of which there is lots of literature. The key element of how channels and go routines play into thi
