Use when working with the rustup CLI — the Rust toolchain multiplexer. Covers installing/updating/uninstalling toolchains, channel syntax (stable/beta/nightly, dated, versioned), cross-compilation targets, components and profiles, directory and file overrides (rust-toolchain.toml), the proxy/shim dispatch system (cargo/rustc/rustdoc/rustfmt/rust-analyzer), `rustup run`, `+toolchain` shorthand, self-management, shell completions, and environment variables. Triggers on: "rustup", "rustup install", "rustup update", "rustup toolchain", "rustup target", "rustup component", "rustup override", "rustup run", "rustup which", "rustup doc", "rustup man", "rustup self", "rustup show", "rustup set", "rustup home", "rustup completions", "rustup check", "rustup default", "+toolchain", "rust-toolchain.toml", "RUSTUP_HOME", "RUSTUP_TOOLCHAIN", "RUSTUP_AUTO_INSTALL", "rustup profile", "rustup proxy", "rust-analyzer proxy", "cargo-miri".

Reference for rustup — the Rust toolchain installer and multiplexer. Covers the full CLI surface, the proxy dispatch system, toolchain resolution, cross-compilation, and configuration.
Command line
→ rustup binary (multi-call: arg0 selects mode)
→ rustup_mode : rustup <subcommand> ... (management)
→ proxy_mode : cargo / rustc / ... (tool dispatch)
→ setup_mode : rustup-init (installer)
→ toolchain resolution
1. +toolchain shorthand
2. RUSTUP_TOOLCHAIN env var
3. rustup override (dir override, closest wins)
4. rust-toolchain.toml / rust-toolchain file (closest wins)
5. default toolchain
→ install-on-run (if RUSTUP_AUTO_INSTALL=1)
→ exec real toolchain binary with configured env
