//! `outlayer update` — self-update the CLI to the latest GitHub release.
//!
//! Uses the `self_update` GitHub backend, which matches the release asset for
//! the current platform (target triple, e.g. `aarch64-apple-darwin`) built by
//! `.github/workflows/release.yml`, downloads it, and atomically replaces the
//! running binary. Releases are cut on git tags, so `update` only sees a new
//! version once a tagged release has been published.

use anyhow::{Context, Result};

/// Repo hosting the release artifacts (see `.github/workflows/release.yml`).
const REPO_OWNER: &str = "out-layer";
const REPO_NAME: &str = "outlayer-cli";
/// Binary name inside the release tarball (`BINARY_NAME` in release.yml).
const BIN_NAME: &str = "outlayer";

/// Check GitHub releases for a newer version and replace the running binary.
///
/// **Blocking** — `self_update` uses `reqwest::blocking`, which spins up its
/// own runtime and panics if called from within an async context. The
/// dispatcher MUST run this via `tokio::task::spawn_blocking`.
