Deferreds can be passed around, just like regular objects, but cannot be asked for their value. A deferred is an instance of a class designed to receive and process a result which has not been computed yet, for example because it is based on data from a remote peer. Naturally, such protocol code will fail ( raise an exception) if the transport layer does not support such semantics.Ĭentral to the Twisted application model is the concept of a deferred (elsewhere called a future). Note that it is still possible, in protocol code, to deeply query the transport layer on transport issues (such as checking a client-side SSL certificate). The logical protocol is informed of the transport layer instance, and can use it to send messages back and to check for the peer's identity. Connection between a logical protocol and a transport layer happens at the last possible moment - just before information is passed into the logical protocol instance. Twisted is designed for complete separation between logical protocols (usually relying on stream-based connection semantics, such as HTTP or POP3) and physical transport layers supporting such stream-based semantics (such as files, sockets or SSL libraries). 1.1 Separation of protocols and transportsĬore ideas Separation of protocols and transports.Import Navbar from './components/Navbar' Import(/* webpackChunkName: "about" */ "./views/ProductInfo.vue"), Import(/* webpackChunkName: "about" */ "./views/Checkout.vue"), Import(/* webpackChunkName: "about" */ "./views/About.vue"), which is lazy-loaded when the route is visited. this generates a separate chunk (about.js) for this route Import(/* webpackChunkName: "about" */ "./views/AdminLogin.vue"), I have mutations but did not think they'd be needed If (typeof(securit圜ode) !='undefined' & securit圜ode.toString().length = 6) ) Ĭommit('setLoginFlag', _flag) Ĭommit('setNoPasswordMatch', _no_match) Ĭommit('setUserNotFound', _found)
