Why are you using D instead of Rust

Why did you pick Rust specifically?

I am not using either for anything that matters. Mostly because I 
haven't found a case where D or Rust provided a foundation to 
build on that others don't. Rust, as a language, is trying to 
solve a problem I usually don't have, at a significant modeling 
cost.  Their approach might be worthwhile for larger executables 
built by larger teams.

Rust seems to have one major feature (tracking resource use). D 
is trying to provide all features and not really excelling at any 
particular domain. What prevents D from pursuing a multi paradigm 
approach is that it lacks a modular compiler implementation, so 
it has hit an evolutionary wall.

Rust has more of a cultural wall that will keep it true to its 
main focus, but that also prevents evolution. Rust and C++ 
attract programmers that accept complexity, as such, they are 
likely to become more complex over time. So programmers that feel 
those languages are difficult to learn are unlikely to be happy 
with where they are heading. Some might argue that D has 
comparable cultural challenges.

Right now it is difficult to say where D is heading. Seems to me 
that a restructuring of the compiler is needed, but there does 
not seem to be plan for it, so it is ulikely to happen.
