Could you build this?
No Building a performant (La)TeX compiler in Rust requires deep compiler engineering and mastery of Knuth's complex typesetting and macro expansion algorithms.
What it would actually take: A TeX compiler demands an intricate macro expansion engine with dynamic scoping, Knuth-Plass line-breaking and paragraph-formatting algorithms, complex mathematical formula layout routines, and font metric parsers (TFM/OpenType). Implementing this in Rust requires systems-level architecture design, extensive unit testing against the TeX 'trip' test suite, and deep knowledge of the TeX rendering model.
