Can you clarify what you mean by this? Which rock solid C libraries are there for working with images? I'm not talking libpng and libjepg but higher level stuff. Because most people do not use those libraries directly because they are too low level. So any higher level library is a welcome addition.
Most programming languages currently have some agreed upon image library (like PIL/Pillow in Python) and they are not standing on good foundations either.
I don't have anything against rust and i would read a blogpost that details what they gain from switching to a rust-based library. But i am a bit frustrated by my subjective perception that recently there were a lot of posts on the frontpage that just do something in a fancy language.
