Inspired by <a href="https://elm-lang.org/">Elm</a>.</p> <h2 id="disclaimer"><a class="doc-anchor" href="#disclaimer">§</a>Disclaimer</h2> <p>iced is <strong>experimental</strong> software. If you expect the documentation to hold your hand as you learn the ropes, you are in for a frustrating experience.</p> <p>The library leverages Rust to its full extent: ownership, borrowing, lifetimes, futures, streams, first-class functions, trait bounds, closures, and more. This documentation is not meant to teach you any of these. Far from it, it will assume you have <strong>mastered</strong> all of them.</p> <p>Furthermore—just like Rust—iced is very unforgiving. It will not let you easily cut corners. The type signatures alone can be used to learn how to use most of the library. Everything is connected.</p> <p>Therefore, iced is easy to learn for <strong>advanced</strong> Rust programmers; but plenty of patient beginners have learned it and had a good time with it. Since it leverages a lot of what Rust has to offer in a type-safe way, it can be a great way to discover Rust itself.</p> <p>If you don’t like the sound of that, you expect to be spoonfed, or you feel frustrated and struggle to use the library; then I recommend you to wait patiently until <a href="https://book.iced.rs">the book</a> is finished.</p> <h2 id="the-pocket-guide"><a class="doc-anchor" href="#the-pocket-guide">§</a>The Pocket Guide</h2> <p>Start by calling <a href="fn.run.html" title="fn iced::run"><code>run</code></a>:</p> <div class="example-wrap"><pre class="rust rust-example-rendered"><code><span class="kw">pub fn </span>main() -> iced::Result { iced::run(<span class="string">"A cool counter"</span>, update, view) }</code></pre></div> <p>Define an <code>update</code> function to <strong>change</strong> your state:</p> <div class="example-wrap"><pre class="rust rust-example-rendered"><code><span class="kw">fn </span>update(counter: <span class="kw-2">&mut </span>u64, message: Message) { <span class="kw">match </span>message { Message::Increment => <span class="kw-2">*</span>counter += <span class="number">1</span>, } }</code></pre></div> <p>Define a <code>view</code> function to <strong>display</strong> your state:</p> <div class="example-wrap"><pre class="rust rust-example-rendered"><code><span class="kw">use </span>iced::widget::{button, text}; <span class="kw">use </span>iced::Element; <span class="kw">fn </span>view(counter: <span class="kw-2">&</span>u64) -> Element<Message> { button(text(counter)).on_press(Message::Increment).into() }</code></pre></div> <p>And create a <code>Message</code> enum to <strong>connect</strong> <code>view</code> and <code>update</code> together:</p> <div class="example-wrap"><pre class="rust rust-example-rendered"><code><span class="attr">#[derive(Debug, Clone)] </span><span class="kw">enum </span>Message { Increment, }</code></pre></div> <h3 id="custom-state"><a class="doc-anchor" href="#custom-state">§</a>Custom State</h3> <p>You can define your own struct for your state:</p> <div class="example-wrap"><pre class="rust rust-example-rendered"><code><span class="attr">#[derive(Default)] </span><span class="kw">struct </span>Counter { value: u64, }</code></pre></div> <p>But you have to change <code>update</code> and <code>view</code> accordingly:</p> <div class="example-wrap"><pre class="rust rust-example-rendered"><code><span class="kw">fn </span>update(counter: <span class="kw-2">&mut </span>Counter, message: Message) { <span class="kw">match </span>message { Message::Increment => counter.value += <span class="number">1</span>, } } <span class="kw">fn </span>view(counter: <span class="kw-2">&</span>Counter) -> Element<Message> { button(text(counter.value)).on_press(Message::Increment).into() }</code></pre></div> <h3 id="widgets-and-elements"><a class="doc-anchor" href="#widgets-and-elements">§</a>Widgets and Elements</h3> <p>The <code>view</code> function must return an <a href="type.Element.html" title="type iced::Element"><code>Element</code></a>.
