granular and the size of the job pool can be specified by a flag (-j/--jobs)Parallelism Level 3 - Bazel Same as the level before, but resource- intensive targets can reduce the level of parallelism on-demandParallelism installed tools/libraries that can change between different workstationsReproducibility Level 4 - Bazel Toolchains are treated as normal inputs. This trivially allows defining custom toolchains whilst cachingCaching Level 4 - Bazel Supports file-system and distributed caching as with the previous level, but based on the digest of the input files' content rather than mtime. Bazel also has an in-memory

Soong fills that gap. • Soong 与 Bazel 有许多相似之处，后者是 Blaze 的开源变体（在 google3 中使用）。 • 我们计划逐渐在 Android，ChromeOS 和 Fuchsia 中采用 Bazel 进行开发。 • 对所有 Rust 操作系统开发者而言，了解类似 Bazel 的构建规都很有用。 • 趣味小知识：《星际迷航》中的数据是 Soong interpreted language). – 如要加入 Rust 生态系统，必须使用 Cargo 等标准 Rust 工具。如果希望库获得外部贡献，并且 能够用于除 Chromium 之外（例如用于 Bazel 或 Android/Soong 构建环境）的项目，则应该 使用 Cargo。 • 基于 cargo\ 的 Chromium 相关项目示例： – serde_json_lenient（已在 Google
