I have seen \Magento\Framework\Module\ModuleListInterface $moduleList implemented in a custom module like that

$this->_moduleList = $moduleList;
public function getExtensionVersion()
{
    $moduleCode = 'My_Module';
    $moduleInfo = $this->_moduleList->getOne($moduleCode);
    return $moduleInfo['setup_version'];
}

My question is, What is the purpose of this interface and which methods we can invoke using this interface?

The purpose this class is to get the information about modules. Use these methods using ModuleListInterface.


  namespace Magento\Framework\Module;
  interface ModuleListInterface
   {
     public function getAll();
     public function getOne($name);
     public function getNames();
      public function has($name);
   }

    The methods do what their names suggest: getAll - retrieves you info about all installed modules, getOne - gets you info about a specific module, getNames gets you the names of the installed modules and has checks if a module exists without retrieving the info.
