Podjetje KDAB je napovedalo razvoj komponente Servo WebView za Qt, ki uporablja brskalni\u0161ki motor Servo namesto modula Qt WebEngine (ki temelji na Chromiumu) za prikazovanje spletne vsebine v QML aplikacijah. Predvideva se, da bo projekt pomagal zmanj\u0161ati povr\u0161ino napadov na Qt aplikacije, ki uporabljajo API WebView, z uporabo komponente, v kateri je s pomo\u010djo jezika Rust minimalizirano tveganje za ranljivosti, ki izhajajo iz napak pri upravljanju z pomnilnikom. Koda Servo WebView za Qt se distribuira pod licenco MPL-2.0. <\/p>\n

Za organizacijo delovanja kode Servo, napisane v jeziku Rust, v okolju v jeziku C++, je vklju\u010dena plast CXX-Qt. CXX-Qt omogo\u010da ustvarjanje komponent v jeziku Rust, ki se integrirajo s programi v C++, ki uporabljajo Qt. Uporaba CXX-Qt omogo\u010da ustvarjanje podrazredov QObject v Rustu, ki se lahko uporabljajo v kodi v C++, QML in JavaScript. Prav tako je mo\u017ena izdelava Rust programov, ki kli\u010dejo kodo v C++, za kar so na voljo Rust ovitki nad tipi\u010dnimi razredi QtCore in QtGui. <\/p>\n

Projekt Servo se je sprva razvijal pod okriljem podjetja Mozilla, nato pa je pre\u0161el pod okrilje organizacije Linux Foundation. Motor se razlikuje po podpori ve\u010dnitnemu upodabljanju spletnih strani, paralelizaciji operacij z DOM (Document Object Model) in izkori\u0161\u010danju mehanizmov varnega programiranja, ki jih ponuja jezik Rust. Ob ustanovitvi Servo brskalni\u0161ki motor Firefox ni mogel v celoti izkoristiti potenciala sodobnih ve\u010djedrnih sistemov zaradi uporabe enonitnih shem obdelave vsebin. Servo je bil sprva ustvarjen s podporo delitvi kode DOM in upodabljanju na manj\u0161e podnaloge, ki jih je mogo\u010de izvajati vzporedno in bolj u\u010dinkovito izkori\u0161\u010dati vire ve\u010djedrnih CPU-jev. V Firefoxu so \u017ee integrirani nekateri deli Servo, kot so ve\u010dnitni CSS motor in sistem upodabljanja WebRender. <\/p>\n

Med sorodnimi projekti se prav tako izpostavlja projekt Tauri-Servo, ki razvija zadnji del knji\u017enice WRY na osnovi motorja Servo, kar omogo\u010da uporabo Servo v aplikacijah na osnovi ogrodja Tauri (konkurentska platforma z Electron za ustvarjanje uporabni\u0161kih aplikacij z uporabo brskalni\u0161kih tehnologij).
