Composition of interfaces in Go

Question

Is there a way to make an interface also include the methods defined by another interface in Go?

For example:

type BasicDatabase interface {
    CreateTable(string) error
    DeleteTable(string) error
}

type SpecificDatabase interface {
    CreateUserRecord(User) error
}

I would like a way to specify that the SpecificDatabase interface contains the BasicDatabase interface. Similar to the way Go lets you do composition of structs.

This way my methods can take a type that implements SpecificDatabase, but still call CreateTable() on it.

Answer 1

This can be done the same way as when composing structs.

type BasicDatabase interface {
    CreateTable(string) error
    DeleteTable(string) error
}

type SpecificDatabase interface {
    BasicDatabase
    CreateUserRecord(User) error
}
