What it does

This interface defines a contract for collecting shipping rates for a quote address in Magento 2.

Developers implement this interface to create custom shipping rate collectors that gather available shipping methods and their costs based on a rate request.

It's primarily used during checkout when the system needs to determine shipping options for the customer's cart.
