AFAIK a very large part of Slang are massively big 3rd party libraries written in C++, the Slang-specific Rust code would just be a very thin layer on top of millions(?) of lines of C++ code that has been grown over decades and is maintained elsewhere.

(fwiw I've been considering to write the custom parts of the Sokol shader compiler in Zig instead of C++, but that's just a couple of thousand lines of glue code on top of massive C++ libraries (SPIRVTools, SPIRVCross, glslang and Tint), and those C++ APIs are terrible to work with from non-C++ languages.

As far as developer friction for integration into asset workflows goes, that's exactly where I would prefer Zig over Rust (but a simple build.zig already goes most of the way without porting any code to Zig).
