rustbook

This repository is for my workings through The Rust Programming Language book, commonly known as "The Rust book".

Conventions

• rustup is used for version management
• Indentation is handled with four spaces
• Cargo is used for package management and building systems
• Variables and references are immutable by default

Symbols

• Most Rust lines end with a semicolon ;
• Rust functions are invoked with functionName()
• Function bodies are wrapped in curly braces {}
• Rust macros have an exclamation mark after their name !
• Associations for libraries, functions and type are marked with a double colon ::
• Access a specific piece of code from reference &
