🏗️ Project Structure

Cargo Project Names

• Must be written in snake_case format
• Example: my_rust_project

Rust Projects

• Projects in Rust are also known as packages or crates
• Two main types of crates:
  • 📦 Binary Crate: Standalone application meant to be executed
  • 📚 Library Crate: Code intended to be used by other projects

Target Directory

• Located in ./target/
• Contains compiled artifacts:
  • Executable files
  • Debug symbols
  • Intermediate compilation files
• The final executable program is stored here after compilation

📄 Project Configuration

Cargo.toml

• Main configuration file for Rust projects
• Contains:
  • Project metadata
  • Dependencies
  • Build settings
  • Package information

🛠️ Commands Reference

Essential Cargo Commands

• cargo new <project_name> - Create a new Binary crate or Rust project
• cargo build - Compile the project in debug mode (larger file size, includes debug info, faster compilation)
• cargo build --release - Compile the project in release mode (smaller file size, optimized performance, longer compilation time)
• Note: Always start with cargo build for debugging and development, then use cargo build --release for final production builds
• cargo run - Compile and run the project in one command (no need to run cargo build first)
• cargo check - Quickly verify if your code has any compilation errors (syntax errors, type mismatches, missing dependencies, etc.) without creating an executable file (faster than cargo build)
• cargo test - Run project tests

📝 Type and Size of Variables

• Rust requires the type and size of a variable to be known at compile time
• This is important for memory safety and preventing runtime errors
• Rust is a statically typed language, which means it checks the types of variables at compile time
• By knowing the type and size of a variable at compile time, Rust can allocate the necessary memory and prevent common errors like buffer overflows

📝 Notes

• Keep your code organized and follow Rust's conventions
• Use cargo doc --open to generate and view documentation
• Check rust-lang.org for official documentation
