Yes, you’re correct trend is the wrong term. Was that an aggressive statement? It wasn’t intended to be.
I find the statements around unsafe in Rust to generally be incorrect though, from what I can tell, it’s only ever used in quite narrow cases and not generally across the vast majority of Rust software.
Isn’t that an FFI boundary though? There are a lot of examples of FFI crates where the inner FFI is wrapped by an outer safe crate with a Rust API.
Not having looked at that API specifically, it might be that they think there are perhaps different approaches to implementing the safe interfaces, and those may be best left to specific implementations for UI abstraction frameworks, like Druid.
