How Do I Import and Use a Struct from Another Go Package?

Import Struct from Another Package and File

Importing a type from another package can be challenging, especially when coming from a language like Java. Let's explore how to resolve this issue in Go.

In Go, importing is not about types or functions but about packages. To import a package, use the import keyword followed by the package path. This allows you to access the exported identifiers within that package using packagename.Identifiername.

However, the struct you provided exists within a type declaration inside the imported package. To access it, you need to import that package into your current file. This can be done by placing an import statement at the top of the file where you want to use it.

For example, let's assume the PriorityQueue struct is defined in a package called "queue":

package main

import "queue"

func main() {
  pq := &queue.PriorityQueue{}
}

Now, you can use the PriorityQueue type as needed within your program.

Importing packages enables you to reuse and extend existing code, fostering modularity and code maintainability. Remember to consider package names carefully to avoid naming conflicts and ensure code organization.
