Efficient, deferred formatting for logging on embedded systems
knurling-rs/defmt 的健康指数为 100 分中的 88 分,处于「优秀」区间。 其得分最高的类别是Vitality(86/100),最低的是AI Readiness(50/100)。 最近一次更新在今天。 近期的大部分工作由 2 位贡献者完成。
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,再依据公开记录的分布进行校准,使各等级具有百分位含义;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 34(存在风险)的上限。
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。
加权总体分 74 经校准后在公布的指数量表上为 88(记录校准 2026-08-02)。

每颗 star 和每个 fork 的添加时间,来自 GitHub 并按天汇总。累计增长位于其构成来源——每日新增——的正上方,二者可相互对照:稳定的自然增长与短暂的突增形态截然不同。当这一差别可被衡量时,它会作为增长真实性予以报告。
每个点涵盖 6 天。

本报告未能采集到解析后的依赖集合:GitHub dependency-graph SBOM unavailable (404); the dependency graph may be disabled for this repository
安装 crates:defmt@1.1.1 会引入 28 个包(直接与传递):其中 0 个存在已知公告,0 个为直接依赖。
没有已知公告影响已评估的依赖。
公告表示依赖图中记录的版本落入某条公告的受影响范围。可达性未经分析,且依赖图包含开发与测试的版本固定——某项发现可能只涉及工具链而非交付的软件。
