Rust version is 1.20.0 and I'm on Windows 10.

[stevepentland]

I don't believe those portions of libc are available on the Windows version. I've been searching the crate source and it only seems to be unix-like systems that provide them.

[sharkdp]

Unfortunately, Windows is not supported at the moment (precisely due to rusage which is used to measure user/system time in addition to the wall-clock time). If there is some support for a Windows version, we might prepare a stripped down version that simply does not report user/system time.

Could you try to compile v0.2.0 of hyperfine on Windows?

[TheInitializer]

v0.2.0 seems to work fine. It doesn't output some characters though (which might just be my terminal emulator):

λ hyperfine "python -c \"print(4)\""
Benchmark #1: python -c "print(4)"                                                                                       0

  Time (mean ± σ):     408.7 ms ± 1030.9 ms

  Range (min … max):    21.7 ms … 3340.5 ms

Closed via #32 (see also #33).
