Is cuda_std still maintained?

Hi, I am currently working on my own cuda bindings for rust. I was looking for some implementations for basic math functions in cuda kernels, and I came across this project. I tried compiling cuda_std targeting nvptx but I got a lot of compiler errors related to missing imports + removed features. Is cuda_std still maintained? I noticed that the last changes were 4+ years ago. Is there something else yall are using now?
