Ah, this is a codec guy. That yields an unusual list of desired features. Bit-pushing predominates. Inline assembler and access to SIMD instructions is important. Speed in tight loops is essential.
Their wishlist is composability, being able to write performant code, being able to perform other low-level operations, being able to use assembly and a reasonably easy build system.
I'd argue that's not just a fairly common list of desired features but that if there's more than 1 of those desires not in your own list then there's probably better languages than Rust to consider.
