Is it possible to do this in golang?

I have a doubt about the .yaml files in golang, suppose I have a .yaml file with the following content:

print:
  1

print:
  2

print:
  3

Is there a way to get all the print in the yaml file? How would I represent that structure in golang? Because for example if I have this in a .yaml file:

print:
  1

In golang I can represent it like this:

type Print struct {
  Print int `yaml:"print"`
}

And if that cannot be done, what other way would there be to do something similar? Thanks in advance.

Your YAML is not legal. You can't have the same key multiples times in a mapping. From 3.2.1.1 of the spec...

The content of a mapping node is an unordered set of key/value node pairs, with the restriction that each of the keys is unique.

Instead, use a mapping to a sequence.

print: [1,2,3]

And store it as an []int.

type Print struct {
  Print []int `yaml:"print"`
}
