Emit hdf5 version as a build constant

[magnusuMET]

Hopefully this works for you @philbucher. It is re-exported in hdf5 and the version is visible in the generated docs.

Fixes #47

thanks for the fast response, this is awesome!
I will try asap this week!

I tried to include your repo in my project with
hdf5 = {git = "https://github.com/magnusuMET/hdf5-rust.git", branch = 'const_hdf5_version'}

but I get the following error:

error: no matching package named `hdf5` found
location searched: Git repository https://github.com/magnusuMET/hdf5-rust.git?branch=const_hdf5_version

I have the feeling that this might be because the hdf package does not exist in the default branch, but unsure.
Maybe you could rebase your default branch to update to the latest version?

Or not if thats too much work, to me the code looks ok as is, I can also test once its merged

Thanks again!

The package is named hdf5-metno. You should be able to do a simple patch by adding the following to your Cargo.toml (this is overriding the dependency):

[patch.crates-io]
hdf5 = { package="hdf5-metno", git = "https://github.com/magnusuMET/hdf5-rust.git", branch = "const_hdf5_version" }

now I got it to work, thanks!
Works perfectly
