Crate grex did not build

[pemistahl]

Crate name: grex
Build failure link: https://docs.rs/crate/grex/0.3.1/builds/210840

Additional details:
The problem is dependent crate matrixmultiply v0.2.3.
The error is array lengths can't depend on generic parameters.
This bug has been reported already in bluss/matrixmultiply#50.
Seems to be a problem with the current Rust nightly as reported in rust-lang/rust#67743.

Ping me when this gets fixed upstream and I can manually schedule a rebuild. This is hard to fix in general, see #464 and #506

[pemistahl]

I'll do. It is really unfortunate that you cannot use an older nightly or stable Rust for building the docs. This would solve the problem instantly.

Using stable is unfortunately not possible, as docs.rs uses (a lot of) unstable features to build documentation. Using another nightly is... doable, but complicated :(

@jyn514 This is fixed in the upstream nightly. I also have an affected crate, netcdf that needs a rebuild due to the same error.

@magnusuMET Thanks for letting me know. Yes please, a rebuild of the docs for crate grex, versions 0.3.1 and 0.3.2 would be great. Thanks in advance.

I rebuilt grex 0.3.1, grex 0.3.2, and netcdf 0.4.0.
