Loading & Error States

Show spinners and handle failures gracefully.

Every Fetch Has Phases

A real request moves through states: loading, success, and failure. Showing each one makes your app feel trustworthy. 🔄

Modeling State with an Enum

An enum captures each phase cleanly. The view then switches on it to decide exactly what to display.

enum Phase { case loading, loaded([User]), failed(String) }
