  • Rust 1.83.0 から、lockfile v4 が default になった
  • ところで、Renovate が依存を更新する時は、内部で cargo update が叩かれている
    • そして、(おそらく)Renovate のコンテナが抱えている Rust のバージョンで更新が行われる
    • Cargo.lock が v4 になった状態で commit される
  • しかし、lockfile v4 は 1.78.0 で stabilize された
    • ということは、Rust 1.77.0 以前では v4 な Cargo.lockが発生するとビルドがコケる
  • そのため、一旦 1.78.0 に上げる
