What it says it does

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".

Every number above came out of reading the file and its repository. Nothing is a judgement call, nothing is a model’s opinion, and nothing can be paid for. The full method is published. Source last committed 2026-08-13.

Put this measurement in your README

A badge carrying how many listings this index holds from the repository and how many pass every static structural check. It reads from this index every time somebody loads your page, so it changes when the measurement changes and there is nothing to keep up to date. Free, no account, and the value is not something you or we can set by hand.

Would rather not hotlink us? Every badge is also served in shields.io’s endpoint schema, so shields renders the image and your readers never talk to our domain:
