Reference

The whole of xpui-chrome's public API, by area. It is written for a backend author: someone answering xpui's Chrome trait on top of a drawing library. The host contract is what a backend implements, and design.md is why the choices here are what they are.

Topics

Each page lists every public name in its area with its declaration, its parameters, examples you can copy, and a picture of what it draws. The gate checks every page against the code, so what a page says an item is, the compiler agrees with, and every rust block on them is compiled and run as a doctest.
