fitzgen / bumpalo
A fast bump allocation arena for Rust
fitzgen/bumpalo tiene un índice de salud de 67 sobre 100, lo que lo sitúa en la banda Moderado. Su puntuación más alta es Community & Adoption (74/100) y la más baja, AI Readiness (52/100). Se actualizó por última vez hace 15 días. Una sola persona concentra la mayor parte del trabajo reciente.
67
global / 100Índice de salud del software
Las métricas se agrupan en categorías ponderadas sobre una escala de 1 a 100. El resultado global parte de su media; cuando la evidencia pública activa la Política de Jurisdicciones de Alto Riesgo, la calificación se ajusta y recibe el límite 49 (En riesgo). Preparación para IA queda fuera.
67
Excelente85-100Ejemplar; cumple prácticamente todos los criterios evaluados
Bueno70-84Saludable; carencias menores
Moderado50-69Aceptable con carencias notables; se recomienda revisión
En riesgo30-49Debilidades significativas; su adopción exige cautela
Crítico1-29Problemas graves (proyecto abandonado, un solo mantenedor, sin higiene)
Perfil de puntuación
Cada eje es una categoría. La forma importa más que la media: un proyecto sano llena toda la figura, mientras que un perfil de picos y cráteres indica que la fortaleza en una dimensión enmascara el riesgo en otra.

Evaluación de seguridad independiente y agnóstica en cuanto a herramientas, procedente del proyecto de código abierto OpenSSF Scorecard. Cada comprobación premia una práctica de seguridad, no la herramienta de un proveedor concreto. Las comprobaciones que Scorecard no pudo determinar se marcan como n/d y se excluyen de la puntuación de seguridad (nunca se cuentan como cero).

Avisos de dependencias 2
Instalar crates:bumpalo@3.20.3 arrastra 73 paquetes, directos y transitivos: 2 tienen avisos conocidos, de los cuales 0 son dependencias directas.

|---|---|---|---|---|---|
| atty | 0.2.14 | indirecta | baja | 3 | — |

Un aviso significa que la versión registrada en el grafo de dependencias cae dentro del rango afectado de un aviso. No se analiza la alcanzabilidad, y el grafo incluye fijaciones de desarrollo y prueba: un hallazgo puede referirse al utillaje y no al software distribuido.
