Layout/IndentationConsistency confused with public methods declaration at the top level

[trambui09]

---

Defined public on the top level, without being inside a class. But rubocop gives an error. Though if the file only has the one line that says "public" it doesn't error out.

error appears when:

public

def create_key_asymmetric_decrypt project_id:, location_id:, key_ring_id:, id:
  # [START kms_create_key_asymmetric_decrypt]
  # TODO(developer): uncomment these values before running the sample.
  # project_id  = "my-project"
  # location_id = "us-east1"
  # key_ring_id = "my-key-ring"
  # id          = "my-asymmetric-decrypt-key"

  # Require the library.
  require "google/cloud/kms"

  # Create the client.
  client = Google::Cloud::Kms.key_management_service

  # Build the parent key ring name.
  key_ring_name = client.key_ring_path project: project_id, location: location_id, key_ring: key_ring_id

  # Build the key.
  key = {
    purpose:          :ASYMMETRIC_DECRYPT,
    version_template: {
      algorithm: :RSA_DECRYPT_OAEP_2048_SHA256
    }
  }

  # Call the API.
  created_key = client.create_crypto_key parent: key_ring_name, crypto_key_id: id, crypto_key: key
  puts "Created asymmetric decryption key: #{created_key.name}"
  # [END kms_create_key_asymmetric_decrypt]

  created_key
end

no errors:

public

error:

public 

def test_method 
  puts "testing if it errors out"
end
