 No. Rust started as Graydon Hoare's part-time side project in 2006 and remained so for over 3 years. Mozilla got involved in 2009 once the language was mature enough to run basic tests and demonstrate its core concepts. Though it remains sponsored by Mozilla, Rust is developed by a diverse community of enthusiasts from many different places around the world. The [Rust Team](https://www.rust-lang.org/team.html) is composed of both Mozilla and non-Mozilla members, and `rust` on GitHub has had over [1,500 unique contributors](https://github.com/rust-lang/rust/) so far.
 
 As far as [project governance](https://github.com/rust-lang/rfcs/blob/master/text/1068-rust-governance.md) goes, Rust is managed by a core team that sets the vision and priorities for the project,

 Fast! Rust is already competitive with idiomatic C and C++ in a number of benchmarks (like the [Benchmarks Game](https://benchmarksgame.alioth.debian.org/u64q/compare.php?lang=rust&lang2=gpp) and [others](https://github.com/kostya/benchmarks)).
 
-Like C++, Rust takes [zero-cost abstractions](http://blog.rust-lang.org/2015/05/11/traits.html) as one of its core principles: none of Rust's abstractions impose a global performance penalty, nor is there overhead from any runtime system.

 Given that Rust is built on LLVM and strives to resemble Clang from LLVM's perspective, any LLVM performance improvements also help Rust. In the long run, the richer information in Rust's type system should also enable optimizations that are difficult or impossible for C/C++ code.
