Why use Rust

• Performance metrics
• Memory safety
• Different production usage
  • Cloud and desktop applications
  • Large technology company usage and support
  • Linux kernel
• Programmer preference and productivity
• Advanced programming
  • Meta programming
  • Foreign function interfaces (FFI) to call code written in other programming languages

Use Cases

• Performance critical applications due to speed and memory efficiency and no garbage collection
• Reduced security vulnerabilities due to memory safety
  • Example: operating systems, user facing systems
• Other examples:
  • Command line applications
