How Can Shared Methods Be Used with Go Generics' Type Union Constraints?

Go Generics: Unlocking Shared Methods in Type Unions

In Go's new generic feature, the type union constraint allows multiple types to be bound to a single generic type parameter. However, the question arises: how can shared methods be utilized across these types?

Initial Attempt and Compiler Error

<br>type AB interface {</p>
<div class="code" style="position:relative; padding:0px; margin:0px;"><pre class="brush:php;toolbar:false">*A | *B

Copy after login

}

func (a *A) some() bool {

return true

}

func (b *B) some() bool {

return false

}

func some[T AB](x T) bool {

return x.some()   // undefined

}

The above code attempts to use the shared some method in function some, but encounters an error, as the compiler cannot determine which some method to call.

Workaround using Interface Constraint

To overcome this limitation, the shared method can be added directly to the interface constraint:

<br>type AB interface {</p>
<div class="code" style="position:relative; padding:0px; margin:0px;"><pre class="brush:php;toolbar:false">*A | *B
some() bool
