描述

The builtin widgets' states should implement standard traits (notably PartialEq) eagerly.

It would be convenient for me to #[derive(PartialEq)] for my app state. Unfortunately, it contains text_input::State which doesn't impl it (but it could).

研究方向
Examine the source code of Iced's builtin widgets (e.g., text input, button, etc.) to find all state structs. For each state struct, determine if all its fields implement PartialEq. If so, add `#[derive(PartialEq)]` to the struct. If some fields are not PartialEq, consider manual implementation or changing field types. The issue specifically mentions `text input::State` as a candidate. Ensure no breaking changes and that the change compiles.
