Benchmarking 20 programming languages on N-queens and matrix multiplication

The rust code is very unidiomatic, not only because of the Vec of Vecs which I’d say, even if it’s the obvious naive approach, no one experienced wouldn’t choose over a flat slice, the implementation itself is very naive and unidiomatic.

Also it's using checked indexing, which apart from being not idiomatic, is also going to slow things down. A fairer comparison would be to use the unchecked indexing variants.

Yeah, it's a similar problem in C# - ported code 1:1 is not representative since it now can't do out of bounds accesses and is therefore safe but comes at a cost of bounds checks which can be manually elided.

Unchecked indexing is unidiomatic. A more fair comparison world be using iterators if possible but otherwise you have to live with that.
