oCAS — open Computer Algebra System.
This crate is the top-level Rust API for oCAS. It re-exports the public items from the lower-level crates so that most users only need one import:
use *;
Backends (GMP, MPFR, FLINT, LLVM, Python, GPL) are opt-in via feature flags to keep the default build portable, including on Windows MSVC where GMP is not readily available.
