Moreover, Rust has the built-in functionality necessary for concurrent execution on multicore machines; it makes concurrent programming memory safe without garbage collection—it is the only language that does this. Rust also eliminates the corruption of shared data through concurrent access, also known as data races.
This enables programs to be fast, but it is inherently unsafe because the memory manipulations allowed by C and C++ are not checked for validity. If the code is written without the utmost programming discipline on the part of the developers, then program crashes, memory leaks, segmentation faults, buffer overflows, and null pointers can occur at program execution. Some of these can result in serious security vulnerabilities, which are all too well-known in existing browsers. Rust is designed from the ground up to avoid these kinds of problems
Rust (http://www.rust-lang.org/) is made to overcome this dilemma by providing the following features:
High safety through its strong type system
Deep but safe control over low-level resources (as much as C/C++) so that it runs close to the hardware
Rust lets you specify exactly how your values should be laid out in memory and how that memory should be managed; this is why it works well at both ends of the control and safety line. This is the unique selling point of Rust: it breaks the safety-control dichotomy that, before Rust, existed in programming languages. With Rust, control and safety can be achieved together without losing performance
