Let's build a simple Feet & Yards to Meters converter web app using Rust and WebAssembly! This guide provides a streamlined approach.

Feet&Yard to meter converter

First, ensure Rust is installed on your system. Download and install it from https://www.php.cn/link/29f81692d9af87c8826aafca8ff5dad3.

Next, create a new Rust project using Cargo:

cargo new yardandfeetconverter

Modify the Cargo.toml file to include the wasm-bindgen dependency and specify the crate type:

[dependencies]
wasm-bindgen = "0.2"

[lib]
crate-type = ["cdylib"]

Navigate to the src directory and rename main.rs to lib.rs. Replace the contents of lib.rs with this conversion logic:

use wasm_bindgen::prelude::*;

#[wasm_bindgen]
pub fn yards_to_meters(yards: f64) -> f64 {
    yards * 0.9144
}

#[wasm_bindgen]
pub fn feet_to_meters(feet: f64) -> f64 {
    feet * 0.3048
}

Build the WebAssembly module:

wasm-pack build --target web

This generates the necessary web files. Now, create an index.html file in the yardandfeetconverter directory. Paste the following code into index.html:

<!DOCTYPE html>
<html>
<head>
  <meta charset="UTF-8">
  <meta name="viewport" content="width=device-width, initial-scale=1.0">
  <title>Yard and Feet to Meters Converter</title>
  <style>
    body {
      font-family: Arial, sans-serif;
      margin: 0;
      padding: 0;
      display: flex;
      justify-content: center;
      align-items: center;
      min-height: 100vh;
      background: linear-gradient(to right, #4facfe, #00f2fe);
    }
    .container {
      text-align: center;
      background: white;
      padding: 2rem;
      border-radius: 10px;
      box-shadow: 0px 4px 10px rgba(0, 0, 0, 0.1);
    }
    input, select, button {
      margin: 10px;
      padding: 10px;
      font-size: 16px;
      border: 1px solid #ccc;
      border-radius: 5px;
    }
    button {
      background-color: #4facfe;
      color: white;
      cursor: pointer;
    }
    button:hover {
      background-color: #00c4cc;
    }
  </style>
</head>
<body>
  <div class="container">
    <h1 id="Feet-Yards-to-Meters-Converter">Feet & Yards to Meters Converter</h1>
    <input type="number" id="value" placeholder="Enter value">
    <select id="unit">
      <option value="yards">Yards</option>
      <option value="feet">Feet</option>
    </select>
    <button id="convert">Convert</button>
    <p id="result"></p>
  </div>
  <script type="module">
    import init, { yards_to_meters, feet_to_meters } from "./pkg/yardandfeetconverter.js";

    async function setup() {
      await init();
      document.getElementById('convert').addEventListener('click', () => {
        const value = parseFloat(document.getElementById('value').value);
        const type = document.getElementById('unit').value;
        let result;
        if (type === 'yards') {
          result = yards_to_meters(value);
        } else {
          result = feet_to_meters(value);
        }
        document.getElementById('result').innerText = `Result: ${result.toFixed(4)} meters`;
      });
    }
    setup();
  </script>
</body>
</html>

Start a local web server (e.g., using Python's http.server):

python -m http.server

Open your browser and navigate to localhost:8000. You can now convert feet and yards to meters!
