In terms of ecosystem, Rust is where C++ was 30 years ago.

While its ideas might seem to be a risk to C++, specially since 
there is no way to fix unsafe by default in C++ without breaking 
backwards compatibility.

However until we get Metal rewritten in Rust, CUDA Rust, 
Tensorflow/Pytorch rewritten in Rust, LLVM/GCV rewritten in Rust, 
AUTOSAR and SYSCL move from C++ to Rust, Nintendo/Sony/Microsoft 
console SDK support for Rust, CERN, Fermilab, NASA moving away 
from Fortran/C++.....

There is no market share for Rust to take away from C++ on those 
domains.

Currently D has more to lose against Rust than C++, because it 
lacks such deep ingrained industry support, and trying to be just 
like Rust won't be differentiating factor.
