DI is generally not an explicit thing in Go. As a sibling comment mentioned, there is wire but it simply generates code, it is not a runtime DI framework like Spring has. This is a feature. The code wire generates is the same code you’d normally write, which is what makes it unnecessary for many projects.

Go has interfaces natively which are implemented in a different way. We never need to say X implements I like we do in other languages. X either satisfies the interface or it doesn’t and the compiler and editor catch this fact early.

So, you’d simply declare an interface to define the API you described in Go, no need for DI or anything else.
