Following example code

[bojohnson5]

I'm attempting to use this library with a project I'm working on. I'm using the code example in the README but get warnings about using the blosc feature

I'm on MacOS and have installed hdf5 and c-blosc2 via Homebrew and compiled and installed the blosc plugin. What's the best way to get blosc compression working, or is it not really needed or are there other compression libraries I could use? I'm just starting to figure what hdf5 is and how it works!

If you set the blosc-all feature you can use blosc freely. In that case you can remove #[cfg(feature="blosc")] as you know this functionality is available

[bojohnson5]

Can you help me understand the purpose of the #[cfg(feature="blosc")] in the example code? It's not something I've used in Rust code before.

They are Features which is there for conditionally including some functionality. blosc is in this case under a feature to save on compilation time

Great, thanks for the reply!
