rust

The ev crate's sources — one library per Cargo feature, so a consumer compiles only what it enables. The thin virtual workspace that anchors the crate for repo-root tooling is ../Cargo.toml.

Unlike architecture, the uikit feature carries runtime deps (dioxus, tailwind_fuse) — a UI kit can't be zero-dep. It mirrors the @evinvest/uikit TypeScript package and ships the shared design tokens; see its rustdoc and ../ts/uikit/README.md.

analytics, error_monitoring, and experiments likewise carry runtime deps and do network I/O (PostHog / Sentry), gated per-target so native and browser backends stay separate — native uses reqwest(rustls)/sentry, wasm uses pure-Rust HTTP behind the wasm feature. Each mirrors its TS package (@evinvest/analytics, @evinvest/error-monitoring, @evinvest/experiments); see their rustdoc and READMEs.

Each feature mirrors a TypeScript package in ../ts. cargo runs from the repo root — pass -p ev for feature flags. See ../docs/ARCHITECTURE.md.
