Shadowing in Rust

Karthic Rao — Wed, 18 Jan 2023 07:47:46 +0000

While Rust comes with strict static typing, surprisingly it supports the concept of Shadowing for types. Shadowing allows variable that was once declared as one type to be redeclared as a new type. In effect, shadowing or overwriting the previous declaration.

Let's take a quick look at Shadowing in Rust. Here's an example of the beginner's favorite guessing game example.

Take a look at line number 10 and 15, and observe that the variable guess is declared. First time as a mutable string, and then as an immutable unsigned 32-bit integer.

Shadowing lets us re-use the guess name, rather than forcing us to come up with two unique names like guess_str and guess, or something else.

What is Dyte?

Dyte is a SDK which provides the easiest way to add real-time communications using audio and video to your apps and platforms.

Features

Real-time, fast communications

Dyte is blazingly fast.

Video capabilities to your mobile apps

Dyte enables you to build Video calling capabilities for mobile

Video capabilities to your web apps

Dyte Enables you to build Video calling capabilities for Web

Audio apps

Dyte offers audio capabilities too.

Web and mobile applications

Dyte can power both mobile and web applications

How dyte works?

Dyte is based largely on the WebRTC protocol, and the features and optimisations we build on top of it.

Although the protocol is supposed to be peer-to-peer, it is not easy to build it reliably.

Anyone who has tried implementing it by themselves would know that the implementions get real messy, real fast.

To have a real working solution, servers with SFU, STUN, TURN, etc capabilities.

This is required to optimize for user bandwidth.

Also to optimize for performance.

Architecture

Here is the architecture of Dyte, and all the step that goes behind the scenes in setting up a meeting.

Using JS SDK

Initialising

Here are the steps to initialise the Dyte JS SDK

Get meeting room name from the backend API
Get participant token form the backend API
Pass them as props to Dyte's React Component to initialize

Using JS React SDK

You can initialize a meeting in your React app, using this component, like below.

import { DyteMeeting } from "dyte-client";

function App() {
  return (
    <div className="App">
      <DyteMeeting
        onInit={(meeting) => {}}
        clientId={`orgId || clientId`}
        meetingConfig={{
          roomName: `roomName`,
          authToken: `authToken`,
        }}
      />
    </div>
  );
}

export default App;
