David Weston, vice-presidente da Microsoft respons\u00e1vel pela seguran\u00e7a do sistema operacional Windows, compartilhou informa\u00e7\u00f5es sobre o desenvolvimento dos mecanismos de prote\u00e7\u00e3o do Windows em sua apresenta\u00e7\u00e3o na confer\u00eancia BlueHat IL 2023. Entre outras coisas, ele mencionou o progresso na utiliza\u00e7\u00e3o da linguagem Rust para aumentar a seguran\u00e7a do n\u00facleo do Windows. Al\u00e9m disso, foi afirmado que o c\u00f3digo escrito em Rust ser\u00e1 adicionado ao n\u00facleo do Windows 11 possivelmente em poucos meses ou at\u00e9 semanas. <\/p>\n

Entre os principais motivos para utilizar Rust est\u00e3o a implementa\u00e7\u00e3o de recursos para uma manipula\u00e7\u00e3o segura da mem\u00f3ria e o trabalho para reduzir erros no c\u00f3digo. O objetivo inicial \u00e9 substituir alguns tipos de dados internos em C++ por tipos equivalentes fornecidos pelo Rust. Atualmente, cerca de 36 mil linhas de c\u00f3digo em Rust foram preparadas para inclus\u00e3o no n\u00facleo. Os testes do sistema com o novo c\u00f3digo mostraram que n\u00e3o h\u00e1 impacto negativo no desempenho no pacote PCMark 10 (teste de aplicativos de escrit\u00f3rio) e, em alguns micros testes, o novo c\u00f3digo at\u00e9 se mostrou mais r\u00e1pido.

\"A<\/center> <\/p>\n

A primeira \u00e1rea de implementa\u00e7\u00e3o do Rust foi o c\u00f3digo DWriteCore, que lida com a an\u00e1lise de fontes. Dois desenvolvedores foram envolvidos no projeto, que levou seis meses para ser conclu\u00eddo. A aplica\u00e7\u00e3o da nova implementa\u00e7\u00e3o reescrita em Rust aumentou a performance na forma\u00e7\u00e3o de glifos para texto em 5-15%. A segunda \u00e1rea de aplica\u00e7\u00e3o do Rust foi a implementa\u00e7\u00e3o do tipo de dado REGION na Win32k GDI (Graphics Driver Interface). Os componentes reescritos em Rust da interface GDI j\u00e1 est\u00e3o passando em todos os testes quando utilizados no Windows, e em breve o novo c\u00f3digo ser\u00e1 inclu\u00eddo por padr\u00e3o em compila\u00e7\u00f5es de teste do Windows 11 Insider. Entre outras conquistas relacionadas ao Rust, destaca-se a tradu\u00e7\u00e3o de algumas chamadas de sistema do Windows para essa linguagem.
