1//! Per-frame UI entry point
2//!
3//! The `Ui` type exposes most user-facing Dear ImGui APIs for a single frame:
4//! creating windows, drawing widgets, accessing draw lists, showing built-in
5//! tools and more. Obtain it from [`Context::frame`].
6//!
7//! Example:
8//! ```no_run
9//! # use dear_imgui_rs::*;
10//! let mut ctx = Context::create();
11//! let ui = ctx.frame();
12//! ui.text("Hello, world!");
13//! ```
