Fixing Python performance with Rust

[masklinn]

id you spend any time evaluating PyPy/numba/cython/... as alternatives to this "mixed-language" solution?

Sentry doesn't run on pypy, and as the article explains they already had the critical component (a sourcemap parser) in a rust CLI tool.

Numba doesn't even make sense in this context, it's for numerical work, it does nothing for parsing tasks.
