Firma KDAB og\u0142osi\u0142a rozw\u00f3j komponentu Servo WebView dla Qt, kt\u00f3ry wykorzystuje silnik przegl\u0105darki Servo zamiast modu\u0142u Qt WebEngine (opartego na Chromium) do wy\u015bwietlania tre\u015bci web w aplikacjach QML. Projekt ma na celu zmniejszenie powierzchni ataku na aplikacje Qt korzystaj\u0105ce z API WebView, dzi\u0119ki zastosowaniu komponentu, w kt\u00f3rym dzi\u0119ki j\u0119zykowi Rust zminimalizowano pojawianie si\u0119 luk bezpiecze\u0144stwa spowodowanych b\u0142\u0119dami w zarz\u0105dzaniu pami\u0119ci\u0105. Kod Servo WebView dla Qt jest dystrybuowany na licencji MPL-2.0. <\/p>\n

Aby zorganizowa\u0107 dzia\u0142anie kodu Servo, napisanego w j\u0119zyku Rust, w \u015brodowisku C++, zastosowano warstw\u0119 CXX-Qt. CXX-Qt umo\u017cliwia tworzenie komponent\u00f3w w j\u0119zyku Rust, kt\u00f3re s\u0105 integrowane z programami w C++ wykorzystuj\u0105cymi Qt. U\u017cycie CXX-Qt pozwala na tworzenie podklas QObject w Rust, kt\u00f3re mog\u0105 by\u0107 u\u017cywane w kodzie w C++, QML i JavaScript. Istnieje r\u00f3wnie\u017c mo\u017cliwo\u015b\u0107 tworzenia program\u00f3w Rust, kt\u00f3re wywo\u0142uj\u0105 kody w C++, dla kt\u00f3rych dostarczane s\u0105 powi\u0105zania Rust z typowymi klasami QtCore i QtGui. <\/p>\n

Projekt Servo pierwotnie rozwijany by\u0142 przez firm\u0119 Mozilla, ale p\u00f3\u017aniej przeszed\u0142 pod skrzyd\u0142a organizacji Linux Foundation. Silnik wyr\u00f3\u017cnia si\u0119 wsparciem dla wielow\u0105tkowego renderowania stron web, r\u00f3wnoleg\u0142ym wykonaniem operacji na DOM (Document Object Model) i wykorzystaniem mechanizm\u00f3w bezpiecznego programowania oferowanych przez j\u0119zyk Rust. W momencie powstania, silnik przegl\u0105darki Firefox nie m\u00f3g\u0142 w pe\u0142ni wykorzysta\u0107 potencja\u0142u nowoczesnych system\u00f3w wielordzeniowych z powodu u\u017cycia jednow\u0105tkowych schemat\u00f3w przetwarzania tre\u015bci. Servo zosta\u0142o pierwotnie zaprojektowane z my\u015bl\u0105 o rozdzieleniu DOM i renderowaniu na mniejsze podzadania, kt\u00f3re mog\u0105 by\u0107 wykonywane r\u00f3wnolegle i efektywniej wykorzystywa\u0107 zasoby wielordzeniowych CPU. Niekt\u00f3re elementy Servo, takie jak wielow\u0105tkowy silnik CSS i system renderowania WebRender, s\u0105 ju\u017c zintegrowane z Firefox. <\/p>\n

W\u015br\u00f3d podobnych projekt\u00f3w warto r\u00f3wnie\u017c wspomnie\u0107 o projekcie Tauri-Servo, rozwijaj\u0105cym backend do biblioteki WRY na podstawie silnika Servo, umo\u017cliwiaj\u0105cym u\u017cycie Servo w aplikacjach opartych na frameworku Tauri (konkurencyjnej w stosunku do Electron platformie do tworzenia aplikacji u\u017cytkowych przy u\u017cyciu technologii webowych).
