description	Manage Rust/Cargo dependencies in this environment. Use when adding, updating, or fetching crates, editing `Cargo.toml`, or working within the constraint that the only approved network command is `cargo fetch` via `run-in-nw-sandbox`.

Rust Dependencies

Overview

Follow the local workflow for Rust dependency updates: manually edit Cargo.toml, then fetch crates using the only approved network command.

Workflow

1. Edit Cargo.toml to add or update dependencies.
2. Fetch crates using the approved network path:

run-in-nw-sandbox -- cargo fetch

3. Continue with normal local builds/tests (no network required).

Guardrails

• Assume the only allowed network command is cargo fetch and it must be run through run-in-nw-sandbox.
• Always include the -- delimiter between run-in-nw-sandbox options and the command.
• Forward environment variables only when explicitly required, using --keep-env=VAR (or --keep-env=VAR1,VAR2) and ensure they are set before forwarding.
• Do not suggest other Cargo network commands (for example cargo update, cargo add, or cargo install) unless the user explicitly confirms network access for them.
