穩定的生鏽

珀西（Percy

在夜間生鏽中，您可以創建文本節點而無需引用。

 // Nightly Rust does not require quotes around text nodes.
html ! { <div> My text nodes here </div> } ;

在穩定的生鏽上，需要引號。

 // Stable Rust requires quotes around text nodes.
html ! { <div> { "My text nodes here " } </div> } ;

一旦跨度位置穩定在Rust編譯器 - 生鏽的跟踪問題中，這種差異就會消失。

入門

提高速度的最佳方法是查看珀西書，但這是一個非常基本的例子，可以弄濕您的腳。

Quickstart-弄濕腳

Percy允許您創建僅具有服務器端渲染的應用程序，僅客戶端渲染，或者服務器和客戶端渲染。

這是您可以立即嘗試的客戶端渲染的快速和愉快的工作示例：

首先，使用

cargo new client-side-web-app --lib
cd client-side-web-app

將以下文件添加到您的項目中。

touch build.sh
touch index.html
touch app.css

這是目錄結構：

 .
├── Cargo.toml
├── build.sh
├── index.html
├── app.css
└── src
    └── lib.rs

現在，用以下內容編輯每個文件：

 # contents of build.sh

#! /bin/bash

cd " $( dirname " $0 " ) "

mkdir -p public

cargo build --target wasm32-unknown-unknown
wasm-bindgen target/wasm32-unknown-unknown/debug/client_side_web_app.wasm --no-typescript --target web --out-dir ./public --debug
cp index.html public/
cp app.css public/

 // contents of src/lib.rs

use wasm_bindgen :: prelude :: * ;
use web_sys ;

use percy_dom :: prelude :: * ;

# [ wasm_bindgen ]
struct App {
  pdom : PercyDom
}

# [ wasm_bindgen ]
impl App {
    # [ wasm_bindgen ( constructor ) ]
    pub fn new ( ) -> App {
        let start_view = html ! { <div> Hello </div> } ;

        let window = web_sys :: window ( ) . unwrap ( ) ;
        let document = window . document ( ) . unwrap ( ) ;
        let body = document . body ( ) . unwrap ( ) ;

        let mut pdom = PercyDom :: new_append_to_mount ( start_view , & body ) ;

        let greetings = "Hello, World!" ;

        let end_view = html ! {
           // Use regular Rust comments within your html
           <div class= [ "big" , "blue" ] >
              /* Interpolate values using braces */
              <strong> { greetings } </strong>

              <button
                class= "giant-button"
                onclick=|_event| {
                   web_sys :: console :: log_1 ( & "Button Clicked!" . into ( ) ) ;
                }
              >
                // No need to wrap text in quotation marks (:
                Click me and check your console
              </button>
           </div>
        } ;

        pdom . update ( end_view ) ;

        App { pdom }
    }
}

現在運行

 # Used to compile your Rust code to WebAssembly
cargo install wasm-bindgen-cli

# Or any other static file server that supports the application/wasm mime type
cargo install https

chmod +x ./build.sh
./build.sh

# Visit localhost:8080 in your browser
http ./public --port 8080
