What is asio in WebSocket?
Who uses Boost ASIO?
The systems software for managing an IBM Blue Gene/Q supercomputer uses Boost. Asio extensively. The source code is available under the Eclipse Public License (EPL) if you’re interested.
What is Boost :: ASIO :: Post?
boost::asio::post posts a given functor into the execution queue and that functor is executed along with other functors and completion handlers in a general way. The function is thread-safe so feel free to post from different threads.
What is Boost beast?
Beast is a C++ header-only library serving as a foundation for writing interoperable networking libraries by providing low-level HTTP/1, WebSocket, and networking protocol vocabulary types and algorithms using the consistent asynchronous model of Boost. Asio.
What is the WebSocket protocol?
The WebSocket protocol enables interaction between a web browser (or other client application) and a web server with lower overhead than half-duplex alternatives such as HTTP polling, facilitating real-time data transfer from and to the server.
What is ASIO networking?
Asio is a cross-platform C++ library for network and low-level I/O programming that provides developers with a consistent asynchronous model using a modern C++ approach.
How does boost ASIO work?
At its core, Boost Asio provides a task execution framework that you can use to perform operations of any kind. You create your tasks as function objects and post them to a task queue maintained by Boost Asio. You enlist one or more threads to pick these tasks (function objects) and invoke them.
Is boost asio post thread safe?
It is safe to post handlers from within a handler for a single instance of an io_service according to the documentation.
What is boost asio Strand?
The boost::asio::bind_executor() function is a helper to bind a specific executor object, such as a strand, to a completion handler. This binding automatically associates an executor as shown above. For example, to bind a strand to a completion handler we would simply write: my_socket.
What is boost Coroutine?
Boost. Coroutine provides templates for generalized subroutines which allow multiple entry points for suspending and resuming execution at certain locations. It preserves the local state of execution and allows re-entering subroutines more than once (useful if state must be kept across function calls).
What is WebSocket vs HTTP?
Unlike HTTP, where you have to constantly request updates, with websockets, updates are sent immediately when they are available. WebSockets keeps a single, persistent connection open while eliminating latency problems that arise with HTTP request/response-based methods.
Is WebSocket better than HTTP?
All the frequently updated applications used WebSocket because it is faster than HTTP Connection. When we do not want to retain a connection for a particular amount of time or reuse the connection for transmitting data; An HTTP connection is slower than WebSockets.
