Rust is the Most Loved Language by Developers
friends of rust
Organizations running Rust in production.
WHAT
System programming language that has great control like C/C++, delivers productivity like in Python and is super safe
Rust is a systems programming language that runs blazingly fast, prevents segfaults, and guarantees thread safety.
Graydon Hoare's personal project started in 2005
-
Sponsored (not owned) by Mozilla since 2009
-
Rust 1.0 since May 2015
-
Current stable version 1.29.2
-
6 weeks release cycle

WHY
Must be this tall to write multi-threaded code
by David Baron
Why should one consider Rust?
-
State of art programming language
-
Solves a lot of common system programming bugs
-
Cargo: Rust Package manager
-
Improving your toolkit
-
Self-learning
-
It's FUN ...
the reason that I’ve looked into Rust at first.
-
Rust is new enough that you can write useful stuff that would have already existed in other languages
-
It gives a relatively familiar tool to the modern C++ developers, but in the much more consistent and reliable ways.
-
It is low-level enough that you take account of most resources.
-
It's more like C++ and Go, less like Node and Ruby
-
cargo is awesome. Managing crates just works as intended, which makes a whole lot of troubles you may have in other languages just vanish with a satisfying poof.
own definition: Rust
Rust is a good choice when you’d choose C++. You can also say, “Rust is a systems programming language that pursuing the trifecta: safe, concurrent, and fast.” I would say, Rust is an ownership-oriented programming language.
Just follow these rules perfectly,
you’re smart.
C/C++

Wait a minute,
I’ll take care of it.
Java and others
Hack without fear!
Rust
Speed
Safety
PARALELLISM
Choose all three!
Zero-cost abstractions
-
Memory safety without garbage collector
-
Threads without data races
OWNERSHIP and Borrowing
Ownership
Mutable borrow
Immutable borrow
fn f(x: Type) {...}
fn f(x: &mut Type) {...}
fn f(x: &Type) {...}
- Total control
- read-write
- one at a time
- read-write
- Share as you like
- read-only
