This is a partial port of nativejson-benchmark to Rust. The libraries tested are:
- serde_json 1.0.72
- rustc-serialize 0.3.24
- simd-json 0.4.11 (this requires a modern x86 CPU for good results)

To update the numbers above, I run ./json-benchmark twice on an otherwise idle computer and take the greater of the two results for each number.
For comparison, here are results from RapidJSON on the same hardware with the nativejson-benchmark modified to run 256 times instead of 10. Code is in the cpp directory of this repo.
