Servo is a modern, high-performance browser engine designed for both application and embedded use. Servo is written in the Rust language. It is currently developed on 64-bit macOS, 64-bit Linux, 64-bit Windows, and Android. As of February 17, 2020, Servo is not yet capable of charset parsing, a feature that all other browsers have. The goal of this project is to implement HTML charset parsing in the current version of Servo.

Introduction

Servo

Servo is an experimental browser engine developed to take advantage of the memory safety properties and concurrency features of the Rust programming language. The project was initiated by Mozilla Research with the effort from Samsung to port it to Android and ARM processors.[2] The prototype seeks to create a highly parallel environment, in which many components (such as rendering, layout, HTML parsing, image decoding, etc.) are handled by fine-grained, isolated tasks.

Rust

Rust is a multi-paradigm programming language focused on performance and safety, especially safe concurrency.[15][16] Rust is syntactically similar to C++,[17] but provides memory safety without using garbage collection.

DOM

  • The HTML DOM is an Object Model for HTML. It defines HTML elements as objects, properties for all HTML elements, methods for all HTML elements, events for all HTML elements.
  • The HTML DOM is an API (Programming Interface) for JavaScript. JavaScript can add/change/remove HTML elements, add/change/remove HTML attributes, add/change/remove CSS styles etc.
