Monotony uses Rust 2024, a pinned nightly toolchain, strict lint settings, and documented library code.
Development builds use Cranelift for debug code generation. On Linux targets,
.cargo/config.toml configures clang with the repository's LLD baseline. Use
make test-fast to opt into mold for faster local test linking. Coverage
generation uses lld because LLVM coverage tools expect LLVM-compatible linker
behaviour.
