Import struct from another package and file golang

In Go you don’t import types or functions, you import packages (see Spec: Import declarations).

An example import declaration:

import "container/list"

And by importing a package you get access to all of its exported identifiers and you can refer to them as packagename.Identifiername, for example:

var mylist *list.List = list.New()

// Or simply:
l := list.New()

There are some tricks in import declaration, for example by doing:

import m "container/list"

You could refer to the exported identifiers with "m.Identifiername", e.g.

l := m.New()

Also by doing:

import . "container/list"

You can leave out the package name completely:

l := New()

But only use these “in emergency” or when there are name collisions (which are rare).
