yosai_libauthz

I'd like to port the entire authorization module from my open source Python project, Yosai, to Rust and use it as a shared library from Python. I PoC'd this work last January, resulting in the release of my first crate and Rust tutorial. I haven't touched Rust since, though, but intend to push on further. A complete Rust implementation has the benefit that it can be adapted to myriad other languages and thus has a much wider audience appeal. It's also about 10x faster than cpython, but pypy may eliminate that gap entirely. Of course there are the usual other benefits, as well. Since Rust is in its infancy for application development, such an authorization library would address a growing need by the Rust ecosystem. If any programmers want in, email me.

Very interesting. I glanced at the code to see if there were obvious performance issues. All I noticed was a triple `map` invocation in https://github.com/YosaiProject/yosai_libauthz/blob/master/s... Not sure what the compiler does with that, but I'd expect that it means you're running through those elements three times. I imagine it would be better to reduce this to one `map` call.

I never got around to talking about it, but as part of my "month of Rust", I ported permission-based authorization logic from Python to Rust and then ran performance benchmarks of the Rust implementation and a pypy-compiled version. The pypy-compiled python ran slightly faster. I've been told not to expect similar results in other implementations. These findings cannot be used to draw any conclusions about pypy.
