What it does

This interface defines a mutex (mutual exclusion) mechanism for shopping cart quotes in Magento 2.

Developers use this to prevent race conditions when multiple requests try to update the same quote simultaneously, such as during concurrent checkout processes or when adding items to cart from multiple browser tabs.

It locks the quote, executes the specified operation, and then releases the lock.
