Rust #

Native WebAssembly component written in PureScript. Requires FluentCI v0.17.2+. Function signatures and argument descriptions come from the compiled PureScript source and are embedded in the component; no raw JSON plugin input is required.

Usage #

fluentci run setup-rust setup --toolchain stable --components rustfmt,clippy --targets wasm32-wasip2,wasm32-unknown-unknown --profile minimal

fluentci run setup-rust --help
fluentci run setup-rust setup --help

See COMPONENT.md for every named argument, description, required flag, and return type. The schema describes the same contract. Optional values retain the native module defaults. List arguments use comma-separated text; boolean arguments accept switches. Native function/flag names use kebab-case.

--toolchain selects a channel, dated nightly, or exact release. --version remains an alias; both must agree when supplied together. --components and --targets accept comma-separated strings installed for that toolchain, with duplicates removed and whitespace around entries trimmed. Omitted or blank values add no components or targets. Empty entries between commas, JSON arrays, and invalid names are rejected before host commands. Profiles are minimal (default), default, and complete. Explicit rustup options fail on BSD, which uses native packages. Failed installation never publishes a successful setup result or activates the installed bin directory.

Requirements and behavior #

Installs and verifies rust, then returns tool, version, bin-dir, and environment (a list of {name, value} records). Environment updates are visible to later tasks in the same host session. Separate shell invocations must add the returned installation directory to PATH explicitly.

Linux/macOS use the configured upstream or ecosystem installer. JavaScript tools are installed through Bun, bootstrapping Node.js/Bun when missing. Python, Go, Ruby, and Java prerequisites depend on the selected tool. BSD uses native pkg, pkg_add, or pkgin repositories; missing packages/versions fail clearly. Nix and Determinate Nix support Linux/macOS only; dpkg/rpmbuild installers are Linux-only.

Development #

From this module directory, with Node.js, Bun, PureScript, and Spago installed:

bun install --cwd ../../lib/component --frozen-lockfile
npm ci
npm run build
npm test

dist/plugin.wasm is the native component; dist/fluentci.metadata.json is its checksummed contract sidecar. The CJS bundles and legacy-entry.mjs exist only for private regression tests and are not the published module interface.
