These two days I have been learning Rust. Unlike Javascript, I would love to learn Rust more throughly since multiple of our projects uses Rust and we are also planning to migrate to Rust for coreos-assembler so it might be very helpful to have good fundamentals.

Here is a summary of unique feature that Rust has comparing to C, Java, Python and Haskell, to which Rust somewhat resembles in some way:

• Rust prevent memory vulnerabilities by taking ownership of memeory (aka one heap memory chunk belongs to only one control block)
• Lifetimes of references
• No null value in Rust

Similarities with other languages:

• Haskell (Functional Programming Languages): Monads,Iterators, Closures, Memoiization (Lazy Evaluation)
• Java (OOP): Traits (Interfaces), Generic Types
• C++: Smart pointers
• C: Channel (Pipe)
