Question about usage documentation

[fedor-rusak]

Context: I want (more like wish) to modify ggez to use rendy under the hood. And use this package later as a dependency for actual project.

Problem:t Made a simple example with rendy having different features for different OS'es. Example. But it fails on Win 10.

Question: How to integrate rendy in helper crate that would work on different Operationg Systems? Is there a documentation for such question?

Sorry if this is not intended use for Rendy package.

The way you wrote Cargo.toml hits cargo own limitations - cargo will try to build dependency with accumulated features even if some are specified under [target.'cfg(<platform_flag>)'.dependencies]

Instead rendy should be buildable with any set of features on any platform. This is the case in branch dedicated to {open,web}gl backend support which should be merged soom™️ .

By the way @icefoxen (ggez author) has plans to power-up ggez with rendy, so you probably should collaborate with him on the matter.

So correct me if I am wrong but intended usage of rendy crate is to create a project for ONE platform and specify only needed features.

I understand that limitations of cargo are beyond scope of Rendy.

Thank you for your response. I assume this integration info already documented and issue can be closed.

Correction. No. Intended usage is to specify all features you need and build on all platforms. But currently required config-macro-magic isn't merged to master so you have to reexport backend features from your crate.
