Include benchmarks on compile speed?

This may be out of scope for this project but it would be interesting to see how long it takes to compile equivalent code using these various crates. Not sure about the best way to measure though, since rustc's self-benchmarking tools are generally nightly only.

I'd quite like to do this, it's a useful metric and something I've been focused on in my own projects. I haven't looked into measuring compile and link time at all so don't have any ideas on how to do it yet.

I don't either, to be honest, besides doing time cargo build and collecting the results or such.

Possibly hyperfine would be a good tool for benching compile times, might be overkill though.

There's also the performance monitoring framework for rust itself that might be good for getting some ideas https://github.com/rust-lang-nursery/rustc-perf

This nightly feature should do the job, just need to parse the json output

cargo +nightly build --release -Z timings=html,info,json
