Seg\u00fan Christoph, tales reglas son in\u00fatiles hasta que sean acordadas con la comunidad y se incluyan en la documentaci\u00f3n del n\u00facleo.      <\/p>\n<p>Christoph tambi\u00e9n se\u00f1al\u00f3 que en las reglas se indica informaci\u00f3n incorrecta respecto a que los mantenedores pueden tomar decisiones por s\u00ed mismos sobre la inclusi\u00f3n de c\u00f3digo relacionado con Rust en sus subsistemas. Seg\u00fan Christoph, en una conversaci\u00f3n privada, Linus Torvalds declar\u00f3 que estaba decidido a aceptar el c\u00f3digo en Rust en el n\u00facleo, a pesar de las objeciones de los mantenedores. As\u00ed, los desarrolladores y mantenedores del n\u00facleo deber\u00e1n lidiar con Rust, quieran o no.       <\/p>\n<p>Christoph tambi\u00e9n volvi\u00f3 a comparar la propagaci\u00f3n de envolturas en Rust con un tumor canceroso que se extender\u00e1 a todos los subsistemas del n\u00facleo y conducir\u00e1 a una fragmentaci\u00f3n. De un todo, el n\u00facleo se convierte en un proyecto escrito en varios lenguajes, sin una clara definici\u00f3n de cu\u00e1ndo se debe utilizar cada lenguaje. Seg\u00fan Christoph, trabajar con una base de c\u00f3digo tan mixta se ha vuelto su peor pesadilla, ya que en tales condiciones el c\u00f3digo se reescribe constantemente de un lenguaje a otro y luego de regreso.    <\/p>\n<p>A su vez, Christoph pide que se le explique el objetivo de la implementaci\u00f3n de Rust en el n\u00facleo. Si el objetivo es resolver problemas de seguridad que surgen al trabajar con memoria a bajo nivel, entonces primero se requiere modernizar el c\u00f3digo existente. Dado que los mantenedores reaccionan de manera dolorosa incluso ante cosas triviales, como las comprobaciones de desbordamiento de enteros, no est\u00e1 claro c\u00f3mo se puede superar la brecha entre una parte del n\u00facleo que ni siquiera acepta reglas simples de seguridad y otra parte que cumple con reglas estrictas. Si el objetivo es simplificar el desarrollo de controladores, entonces introducir el soporte para otro lenguaje solo agregar\u00e1 m\u00e1s trabajo y aumentar\u00e1 la carga sobre las personas que ya est\u00e1n sobrecargadas manteniendo la infraestructura del n\u00facleo en funcionamiento.      <\/p>\n<p>En cuanto a los defensores de la implementaci\u00f3n de Rust en el n\u00facleo, se mencionan los siguientes objetivos:  <\/p>\n<ul>\n<li class=\"l\"> Escribir nuevo c\u00f3digo en el lenguaje Rust reducir\u00e1 el riesgo de errores al trabajar con la memoria y condiciones de carrera, y tambi\u00e9n eliminar\u00e1 algunos errores l\u00f3gicos.\n<li class=\"l\"> A los mantenedores les resultar\u00e1 m\u00e1s f\u00e1cil revisar los cambios y realizar la refactorizaci\u00f3n de m\u00f3dulos teniendo en cuenta las garant\u00edas ofrecidas por el lenguaje Rust.\n<li class=\"l\"> La existencia de abstracciones que utilicen las avanzadas capacidades del lenguaje Rust simplificar\u00e1 la creaci\u00f3n de nuevos controladores y m\u00f3dulos.\n<li class=\"l\"> El apoyo a un lenguaje moderno atraer\u00e1 a nuevos participantes al desarrollo del n\u00facleo.\n<li class=\"l\"> La aplicaci\u00f3n de las capacidades de las herramientas de Rust facilitar\u00e1 el cumplimiento de los requisitos de documentaci\u00f3n del c\u00f3digo. Por ejemplo, en el proyecto Rust for Linux se ha introducido el requisito de documentar obligatoriamente las API p\u00fablicas, los requisitos de seguridad, los bloques unsafe y las invariantes de tipos.  <\/ul>\n<p>Fuente: <a content=\"nofollow\" rel=\"nofollow\" href=\"https:\/\/www.opennet.ru\/opennews\/art.shtml?num=62748\">opennet.ru<\/a>
