The long term future is "uncertain" for both I think. D depends 
on two people and Rust depends on Mozilla. C++ has much much 
wider backing.

Rust is very opinionated and you have to figure out for yourself 
if you want the constraints of linear typing, but the semantics 
are quite clean. D is closer to C++ style templating and OO, and 
currently focus on enabling binding to non-template C++ 
libraries. Rust has more developers behind it. I suggest you read 
Ali's online book and the online Rust tutorial to get a feel for 
both.

D allows you to turn off boundschecks, which should make it 
faster. Currently safe programming in D involves the GC which is 
much easier, but less performant than Rusts linear typing. There 
are those that hope for a comparable non-GC solution for D this 
year, but no concrete description has emerged. Both languages 
have LLVM backends.
