//! cargo-nextest — next-generation test runner for Rust.
//!
//! Homepage: <https://nexte.st>. Roughly 2-3× faster than the built-in
//! `cargo test` on large workspaces (parallel execution, per-test
//! process isolation, better failure reporting).
//!
//! Install path: `cargo install --locked cargo-nextest`. Homebrew ships
//! a formula (`cargo-nextest`) but its bottle is macOS-only, and no
//! first-party winget / apt / dnf packaging exists. Since every user
//! of cargo-nextest is by definition a Rust project, cargo is
//! guaranteed available and gives us a single reproducible install
//! path across every platform Rust supports — matches the pattern
//! established by `release-plz`.

// transfer would need re-verification. As of 2026-07 the crates.io
// owner has not changed since v0.9.
