Introducing the Rust programming languageReidar Sollid

Functional concurrent oriented low level language

2 Presentation Title - Classification

So what is Rust

• A programming language from Mozilla labs •

• Compiled un-managed language• Ahead of time compiler• Concurrent-oriented

• – Message passing– Default immutable variables (mutable keyword)

• • Lambda expressions with a lot if easy to use code• Classes and traits• No NPE crashes, libs use Option<T> or Result<T,U>

• Shared memory is not allowed (Go and Scala does)


What problem to solve

Tasks


Task management

• An Rust program consists of a tree of tasks, with their own stack and sole ownership of allocated heap data

• Communicate through ports and channels

• Propagates failures to its parent (the task spawned this one) unless unsupervise function is called.

• May be executed in parallel and are scheduled by the runtime

• Has its own GC (No global ”stop the world to clean up”)
