A real life use-case for generics in Go: API for client-side pagination

Let’s say we have a RESTful API for a general ledger, with the endpoints, that return a paginated collection of resources: GET /accounts, retrieves a list of accounts, filtered and sorted by some query parameters; GET /accounts/:uuid/transactions, retrieves a list of transactions for account; GET /postings, retrieves a list of postings stored in the ledger.
