Rust Tutorial : Introduction

Application vs Systems Programming Languages
application programming languages like Java/C# are used to build software
provide services to the user directly
used to build business applications like spreadsheets, word processors, web applications or mobile applications

systems programming languages like C/C++ are used to build software and software platforms
used to build operating systems, game engines, compilers, etc.
programming languages can require a great degree of hardware interaction

both face two major problems

  • it is difficult to write secure code
  • it is difficult to write multi-threaded code
Why Rust?

Rust focuses on

  • safety
  • speed
  • concurrency
designed for developing highly reliable and fast software
can be used to write high-level programs down to hardware-specific programs

Performance
Rust does not have a Garbage Collector (GC) by design
improves the performance at runtime

Memory safety at compile time
software built using Rust is safe from memory issues like dangling pointers, buffer overruns and memory leaks

Multi-threaded applications
ownership and memory safety rules provide concurrency without data races

Support for Web Assembly (WASM)
Web Assembly helps to execute high computation intensive algorithms in
  • the browser
  • embedded devices
  • anywhere else
runs at the speed of native code
can be compiled to Web Assembly for fast, reliable execution
