Converting raw u32 to glow::Texture

[Colecf]

Hi, is it possible to take a texture id given as a u32 and wrap it as a glow::Texture? I'm using the openxr crate, which gives you textures to render to as u32s, and I can't figure out how to make them into a glow::Texture, considering NativeTexture's field is private.

error[E0423]: cannot initialize a tuple struct which contains private fields

Hi! 👋 This isn't possible at the moment but you might be able to work around it using transmute temporarily.

I think we could definitely add a function to create a NativeTexture from a u32 handle to support this case. Feel free to add a PR if you'd like, otherwise I'll try to add something soon!

Ah thanks for the tip, transmute does actually work perfectly.

It's kindof a hassle for me to get permission from the company I work for to contribute to open source projects, so I don't think it's worth it for something so small. But thanks for the tip, I'll keep an eye on future releases to see if this gets improved.

Wow that was fast, thanks again!

No problem! The fix is included in the newest release (0.11.2). Please let me know if you run into any other problems with OpenXR integration
