There's a benchmark of languages builtin hashmaps here:

http://vaskir.blogspot.fr/2016/05/hash-maps-rust-vs-f.html

It includes D and Rust. The author found that D wins for the 
lookups but was a bit behind for the insertions (due to GC maybe 
?).

Rust results didn't seem that bad, despite of the cryptographic 
hash function it uses.
