)

// Version - represents the current version of audit log structure.
const Version = "1"

// NewEntry - constructs an audit entry object with some fields filled
func NewEntry(deploymentID string) audit.Entry {
	return audit.Entry{
		Version:      Version,
		DeploymentID: deploymentID,
		Time:         time.Now().UTC(),
	}
