[go-nuts] Golang interface union type parameter
Is Go type parameter supports interface union?
My case
type MessageSpec interface { MessageA | MessageB }
type MessageA interface { ID() uint64 }
type MessageB interface { Uid() uint64 }
but got compile error:
./prog.go:14:2: cannot use main.MessageA in union (main.MessageA contains
methods) ./prog.go:14:13: cannot use main.MessageB in union (main.MessageB
contains methods)
I tried to look for documentation and readed
https://go.googlesource.com/proposal/+/refs/heads/master/design/43651-type-parameters.md#interface-types-in-union-elements
There's example
> type Stringish interface { string | fmt.Stringer }
but it also throwing error
> ./prog.go:19:11: cannot use fmt.Stringer in union (fmt.Stringer contains
methods)
Is this a bug? i know my case is not the same thing as like the one i
referenced from the proposal
but it is throwing the same error.
Thanks

[go-nuts] workspaces tutorial query
I was just taking a look at the workspaces tutorial and saw that while the doc says that adding the local example module will result in go 1.18 use ( ./hello ./example ) what actually results is go 1.18 use ( ./hello example ) The behaviour is otherwise as expected, but this may confuse some readers given that leading dots are important in other paths used by the build system. Should the doc be updated or is the tool's behaviour unexpected here? thanks Dan -- You received this message because you are subscribed to the Google Groups "golang-nuts" group.
