Asynchronous programming in Qt/C++ using tasks,continuations and resumable functions.
This project is inspired by this[1] video on channel9.
The project seeks to do async based programming in Qt/C++ using modern C++ with lambdas.
The project has two sets of APIs.
1. Task::run().then() API provides async based programming with continuation[4].
2. Task::await() API provides the first API presented in a different way[5].
Under certain use cases,they can be used interchangeably, and in others,only one or the other can be used.Some of the problems
the first API causes and solved by the second API are discussed in this[7] youtube video.
Example use case for the Task::run().then() API can be found here[0]. Additional example is [2] where an API is
declared and [3] where the declared API is used.
Example use case of the Task::await() API is here[6] where a function call "blocks" waiting for a result without "hanging" the entire GUI application.
A short tutorial on task/async/await as implemented in C# can be viewed from this[8] link.
