Web Browser Engineering in Rust

A Rust implementation of the Web Browser Engineering book.

Overview

This project is a learning exercise to implement a web browser from scratch using Rust, following the concepts and techniques from the "Web Browser Engineering" book by Pavel Panchekha and Chris Harrelson.

Features

Currently implemented:

• URL parsing (scheme, host, port, path)
• Basic TCP socket connections
• Strong type safety with newtype patterns

Development

This project follows Test-Driven Development (TDD) with strict quality requirements:

• Minimum 50% test coverage (currently at 89%!)
• All tests must pass before committing
• Clippy linting with strict warnings

Build

cargo build

Test

cargo test

Check Coverage

cargo tarpaulin --ignore-tests
