Ettev\u00f5te KDAB teatas Servo WebView komponendi arendamisest Qt jaoks, mis kasutab veebibrauseri mootori Servo asemel Qt WebEngine\u2019i (Chromiumi p\u00f5hjal) QML-rakendustes veebisisu kuvamiseks. Eeldatakse, et projekt aitab v\u00e4hendada Qt-rakendustega seotud r\u00fcnnakupinda, kasutades API-d WebView, t\u00e4nu Rusti keele kasutamisele, mis v\u00e4hendab m\u00e4luhaldusvigade t\u00f5ttu tekkivate haavatavuste loomist. Servo WebView kood Qt jaoks levitatakse MPL-2.0 litsentsi alusel. <\/p>\n

C++ keskkonnas Rustis kirjutatud Servo koodi t\u00f6\u00f6 korraldamiseks kasutatakse CXX-Qt vahekihti. CXX-Qt v\u00f5imaldab luua Rusti keeles komponente, mis integreeruvad Qt-d kasutavate C++ programmidega. CXX-Qt kasutamine v\u00f5imaldab luua QObjecti alamklasse Rustis, mida saab kasutada C++, QML ja JavaScripti koodis. Samuti on v\u00f5imalik luua Rusti programme, mis kutsuvad C++ koodi, mille jaoks on saadaval Rusti sidemed QtCore ja QtGui t\u00fc\u00fcpklasside kohal. <\/p>\n

Servo projekt arenes algselt v\u00e4lja ettev\u00f5tte Mozilla poolt, kuid hiljem v\u00f5ttis selle \u00fcle Linux Foundationi organisatsioon. Mootor eristub mitme l\u00f5ime toel veebilehtede renderdamisel, DOM-i (dokumentide objektimudel) operatsioonide paralleelset t\u00f6\u00f6tlemist ning Rusti keele pakutud turvaprogrammeerimise mehhanismide kasutamisest. Servo loomise ajal ei saanud Firefoxi brauseri mootor t\u00e4iel m\u00e4\u00e4ral kasutada n\u00fc\u00fcdisaegsete mitme s\u00fcdamike s\u00fcsteemide potentsiaali, kuna kasutati \u00fche l\u00f5imega sisu t\u00f6\u00f6tlemise skeeme. Servo on algselt loodud toetama DOM-i koodi ja renderdamise jagamist v\u00e4iksemate alam\u00fclesanneteks, mida saab paralleelselt t\u00e4ita ja t\u00f5husamalt \u00e4ra kasutada mitme s\u00fcdamikuga CPU ressursse. Firefoxis on juba integreeritud m\u00f5ned Servo osad, nagu mitme l\u00f5imega CSS-mootor ja WebRender joonistus s\u00fcsteem. <\/p>\n

Samuti on sarnaste arenduste seas m\u00e4rkida Tauri-Servo projekt, mis arendab WRY teegi tagapinda Servo mootoril ja v\u00f5imaldab Servo kasutamist Tauri raamistiku p\u00f5hjal loodud rakendustes (konkurent Electronile veebitehnoloogiate abil kasutajarakenduste loomiseks).
