How to pass a struct to another package?

Question

go

Let's say I have db.Add(u) where u is of type User. In this function (db.Add), I want to save the structure in the map in order to use it later in this package (create a map with this type). I assume that it is possible to do this (the same gorm uses something similar). I'm just trying to implement a relational database in RAM (without sql, etc. immediately orm that stores everything in RAM for the cache will be the most)

Answer 1

myPackage.go

package myPackage

type User struct {
  ID string
}

func AddUser(user User) {
  // ...
}

package main

import "myPackage"

func main() {
  myPackage.AddUser(myPackage.User{
    ID: "...",
  })
}
