Rust is a system programming language sponsored by Mozilla that aims to be safe, concurrent, and practical. It uses a borrow checker at compile time to prevent common problems like null pointers and data races. Mozilla created Rust in part to build projects like the Servo browser engine. Rust uses Cargo as its package manager and supports features like algebraic data types, pattern matching, and trait-based generics while providing memory safety without garbage collection.

1. A SAFE SYSTEM
PROGRAMMING LANGUAGE

2. AGENDA
 What is Rust ?
 History of Rust
 why would Mozilla sponsor rust
 Goals and features of the rust
 Rust package manager and commands
 Rust applications
 Example program for Rust
 advantages and disadvantages of the rust

3. WHAT IS RUST ?
 Rust is system programming language
sponsored by Mozilla Research. The design to
be a safe, concurrent, practical language.
Supporting Functional and imperative
procedural paradigms.

4. HISTORY OF RUST
 Started as a personal by graydon hoare from Mozilla some
time around 2008.
 Officially recognized as Mozilla sponsored project from 2009
and first announced in 2010.
 First pre-Alpha release in January 2012.
 Currently at 1.16 (stable).
 operating system support for Linux , windows , macOS ,
android , ios etc.

5. WHY WOULD MOZILLA SPONSOR RUST ?
 Want rust for next gen-infrastructure (service , iot).
 Servo is a next generation browser built in rust

6. GOALS OF RUST
Safety - statically typed with extensive compile time
validations.
The system in designed to be memory safe and it does
not permit null pointers , dangling pointer or data races in safe
code.

7.  SPEED: - Compiled , allows low level access similar to C/C++.
For main stream language , I know there different types of programs ,
architecture.
compilation:
Language is translated into MIR
and then compiled with LLVM
RUST MIR LLVM ASM

8.  CONCURRENT :-Built in support for threads , channels
There are two programing using Rust
1)Concurrent programming
2) Parallel programming

9. C/C++
Go
Java
Python
Haskell
RustControl
Safety

10. FEATURES OF RUST
 Zero – cost abstraction
 Algebraic data types (enum )
 Pattern matching
 Trait based generics
 Memory safety without garbage collection

11. Zero-cost abstractons (you pay only for what you use):-
A zero cost abstraction really means that abstraction
doesn’t impose a cost over the optimal implementation of
the task it is abstracting.
Algebric datatypes(enum):- enum means enumeration
data type consisting of a set of named values called
elements , member of the type.it does not use in c.

12. Pattern matching:-
patterns matching are quite common in
rust .
Ex:- let x=1;
match x {
1 => println! (“one”),
2 => println! (“two”),
3 => println! (“three”),
_ => println!(“anything”),
}
 Trait based generic :-
trait are like interfaces , combine traits for polymorphism

13. Rust package manager
 Cargo’s goal is to make modern application package management a core
value of the Rust programming language.
Some common cargo command are:
build compile the current project
doc build this project’s and its dependencies documentation
new create a new cargo project
run build and executes src/main.rs
test run the tests
bench run the benchmarks
update update dependencies listed in cargo . lock
search search registry for crates
publish package and upload this project to the registry
install install a rust binary

14. RUST APPLICATIONS
 Few applications written completely in rust:
 Servo
 Rocket
 Redox
 Habitat

15. WHAT TO DO WITH RUST
 System programming
 Web Browser (Mozilla Firefox)
 Distributed storage system (Dropbox)
 3d Games
 Operating system
 Device drive
 General tools

16. PROGRAM FOR RUST
#[deriving(show)]
enum Direction {
North,
East,
South,
West,
}
fn reverse(dir : Direction)->Direction {
match dir {
North => South,
East => West,
South => North,
West => East,
}
}
fn main() {
println!(“you should head: { }, reverse(North));
}

17. How to compile and run the RUST
program
Filename extensions:- .rs , .rlib
Compile program:-
C: user> rustc < filename >.rs
Run program:-
C: user> rust < filename >.rs

18. ADVANTAGES OF RUST
 Security is it’s biggest advantages
 Memory safety without garbage collection.
 High – performance.
 Provide awesome tools.
 Allow making mistakes.

19. DISADVANTAGES
 Large binary size
 Its almost impossible to run could be unsafe
 Consumes more memory
 Unlike many other languages, Rust doesn’t have
standard way of accessing database

20. CONCLUSION
 Rust is a promising System programming
language.
 Too young to use for fighting in the wild.
 Build enterprise class software with more
confident.
 Run at native speed (C/C+ comparable).
