FlatBuffers: Memory Efficient Serialization Library

C++ · RustApache-2.0★ 26,240 星标⑂ 3,606 复刻始于 2014年5月在 GitHub 上查看 ↗

google/flatbuffers 的健康指数为 100 分中的 40 分,处于「存在风险」区间。 其得分最高的类别是Community & Adoption(96/100),最低的是Security(44/100)。 最近一次更新在 28 天前。 近期的大部分工作由 5 位贡献者完成。

40
总分 / 100
存在风险

软件健康指数

指标归入加权类别,统一采用 1–100 量表。总体分先取类别加权平均;当公开证据触发高风险司法辖区政策时,评级会按政策调整,并设置 49(有风险)的上限。AI 就绪度不计入总体分。

40
优秀85-100堪称典范;基本满足所有检验标准
良好70-84健康;仅有轻微不足
中等50-69可接受,但存在明显不足;建议进行审查
存在风险30-49存在重大薄弱环节;采用时应保持审慎
危急1-29问题严重(项目被弃置、仅有单一维护者、缺乏基本工程规范)
活力社区与采用可持续性与治理工程质量安全AI 就绪度

评分画像

每条轴代表一个类别。形状比平均值更重要——健康的对象会填满整个图形,而“一峰一谷”式画像意味着某一维度的优势正掩盖另一维度的风险。

高风险司法辖区政策对加权总体健康应用 50% 的乘数,并对其设置“存在风险”上限 49。

AI 就绪度

该仓库在多大程度上具备与 AI 编码代理协同开发与维护的条件?这是一枚独立的实验性徽章——权重为 0.0,因此单独呈现,不影响总体健康评分。

依赖安全公告 8

该仓库未发布可被索引解析的包,因此评估的是其自身的依赖图——共 179 个包,其中也包含从不交付的开发与测试版本固定:8 个存在已知公告,0 个为直接依赖。 有 25 个无法评估——没有已解析的版本、生态系统不受支持,或不在所列包清单之内。
