Module theme 

Changing the theme while the application runs, and the palettes that come with it.

LaunchBuilder::with_theme settles the theme once, before anything is drawn, and a const palette rides on it as a &'static reference. An application that lets the reader pick a design system, a scheme or a brand colour at run time needs to send a new SetTheme, and a palette built at run time has no 'static home of its own.

ThemeHandle is that path, and the Dioxus adapter’s use_theme hook hands one out. Setting a theme queues it and it rides out on the batch the current call produces, the way a message does: one record, applied by the Renderer to the whole tree. A palette handed over by value is owned here, so application code never leaks anything to satisfy the lifetime.

Structs

ThemeHandle

A handle on the running theme. Copy, so it can move into any number of handlers.

Functions

current_theme

The theme the application is running with: what it launched with, or what it last set.

own_palette

A palette made at run time, given a home that lives as long as the program.

set_theme

Replaces the whole theme. The Renderer receives it in the batch this call produces.
