A simple to use async/await library for D

dawait - A simple to use async/await library

This library provides a very easy-to-use async/await library for D. It consists of only three functions: async, await, and startScheduler. The library is build on top of D's fibers and allows for easier cooperative multitasking.

Functionality

Function	Description
startScheduler(void delegate() callback)	Starts the scheduler with an initial task.
async(void delegate() callback)	Runs the given delegate in a separate fiber.
await(lazy T task)	Runs the expression in a separate thread. Once the thread has completely, the result is returned.

Code Example

import std.stdio;

int calculateTheAnswer() {
	import core.thread : Thread;
	Thread.sleep(5.seconds);
	return 42;
}

void doTask() {
	writeln("Calculating the answer to life, the universe, and everything...");
	int answer = await(calculateTheAnswer());
	writeln("The answer is: ", answer);
}

void main() {
	startScheduler({
		doTask();
	});
}
