I'm not sure that there's a mature Rust alternative to "all of the above" quite yet. Some things that I've had to build for my own work (not always "built," sometimes I just wrote FFI bindings) include: * N-D dense arrays, fashionably simply called tensors these days ;) (this I wrote from scratch to suit my own needs, but there are several implementations of this in Rust, as well as in C++) * linear algebra (bindings to BLAS, LAPACK etc.) * numerical integration (bindings to GSL or QUADPACK) * optimization and machine learning (this I work on day-to-day) * neural networks (I also work on this) * multicore/manycore/GPU/distributed support (and this) There's also the more practical aspects of using Pandas/iPython (Jupyter)/Spark for data science, including ETL, interactive work, and plotting, which IMO are not quite there yet in the Rust ecosystem. But I think that a lot of the pieces are there, e.g. bleeding fast CSV parsing libraries (https://github.com/BurntSushi/rust-csv https://github.com/BurntSushi/rust-csv), and what's left is the important last mile of bringing these things together in ergonomic libraries or frameworks.
