struct - golang 2 slice types with 1 field -

-

In light of the fact that Golland does not support unions, what is the best way to obtain: 

  Type Fu Structure {word} [string] [] int}

This can be used only for words or nums One thing I may have tried once used in: 

  type foo struct {values ​​[] interface {}}

But I like something that would restrict the type There are two described or something with pointers.

Use a foo package to hide implementation. For example, 

  package foo const (type word = iota + 1 type name) type foo struct {fooType byte words [string string] [int} new word (word [] string) * Foo {Foo (Foo Type: Typed, word: word}} Freak New News (nums [] int) * Foo {Return & amp; FU {Foo Type: TypeNoom, nums: nums}} Function (F * Foo ) Word () [] string {if f.fooType! = Type {return number} return f.deododes} funk (f * fu) names () [] int {if f.fooType! = TypeNums {return nil} Return f.nums}

ADDENDUM:

Since we package Foo is hiding the implementation of , we can apply it in another way, for example, we can take suggestions and use an interface. And add the [] string [/ code>] the phrase . The value types are used to differentiate between two [] string types. / P> 

  package foo type (keyword [] string value speech String Manam [] int) Type Fu Structure {Value Interface {}} Fench New Word (word [] string) * Foo {Return & FU {Value: Value word (word)}} Fench (f * Foo) () [] String {value, ok: fu {returns & amp; Fu} {value: value (phrase)}} function (f * fu) phrase () [] string {value, ok: = f.w.w.E. (Value fee) if! OK {Back Nile} Return Value} Function New News (nums [] int) * Foo {Return & FU {value: valueNums (nums)}} <{Code>   )

Is it possible to specify a dependency on another gradeal project in the granular (in android studios) outside the current project limits? For example, with a relative path like this: dependence {collection project ('../../ stdlib / dagger'}} MyApp (path / user / foo / workspace / mypad) The app (Path / User / Foo / Workspace / MyPass / App) And I have an Android Library Project with 3 subdomules: stdlib (path is / user / foo / Utilities (Path / User / Foo / Workspace / Stadlib / Utilis) http (Path / User / Foo / Workspace / Stadlib / HT) / Li> What I have to do is compile the Dagger, Util, http module in the MyApp project. The Stidelib Library module under heavy development And MyApp will grow in the form of Growth, so I do not want to push them into a Mewen repository. I am a little change. is likely to add another Gredle projects in some way? I will push the study library into the Maven repository after the source is in search of a temp...
