WhatWhatRust is a that combines

strong compile-time correctness guarantees with fastperformance.

It improves upon the ideas of other systems languages likeC++ by providing guaranteed memory safety (no crashes, no

data races) and over the lifecycle ofmemory.

systems programming language

complete control

WhenWhenStarted as a Graydon Hoare's part-time side project in2006 and remained so for over 3 years.

Mozilla got involved in 2009 once the language wasmature enough to run some basic tests and demonstratethe idea

Though it is sponsored by Mozilla, Today, Rust isdeveloped by a diverse community of enthusiasts.

WhyWhyNeed for memory management model, andsimpler concurrent programming constructs toprototype and experiment new browser stacks.Specifically,

Lots of good ideas known and loved from otherlanguages which had not yet made into widely usedsystems languages

FeaturesFeaturesOwnership. model to deal with memory management

Expressive. type inference, higher order functions,pattern matching and algebraic data types

Safe task-based concurrency. Rust's lightweighttasks do not share memory, instead communicatingthrough messages.

Polymorphism. Rust has type-parametric functionsand types, type classes and OO-style interfaces.
