You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: executor_metrics.go
    path of file: ./repos/flyte/flyteplugins/go/tasks/plugins/presto
    
    the code of the file until where you have to start completion: package presto

import (
	"github.com/flyteorg/flyte/flytestdlib/promut
    
func getPrestoExecutorMetrics(scope promutils.Scope) ExecutorMetrics {
	return ExecutorMetrics{
		Scope: scope,
		ResourceReleased: labeled.NewCounter("resource_release_success",
			"Resource allocation token released", scope, labeled.EmitUnlabeledMetric),
		ResourceReleaseFailed: labeled.NewCounter("resource_release_failed",
			"Error releasing allocation token", scope, labeled.EmitUnlabeledMetric),
		AllocationGranted: labeled.NewCounter("allocation_grant_success",
			"Allocation request granted", scope, labeled.EmitUnlabeledMetric),
		AllocationNotGranted: labeled.NewCounter("allocation_grant_failed",
			"Allocation request did not fail but not granted", scope, labeled.EmitUnlabeledMetric),
	}
