Icicle

❄️ Structured Concurrency for C# and dotnet

Why?

Structured Concurrency simplifies concurrent code by treating groups of related tasks as a single unit of work.

Icicle provides a TaskScope which can coordinate a group of concurrent child tasks as a single unit.

The design draws inspiration from JEP 453: Structured Concurrency.

It effectively suspends (freezes ❄️) tasks, returning the user a ResultHandle<T> which represents the promised value once the scope has been run.

using Icicle;

using TaskScope scope = new TaskScope.WhenAll();
// add tasks to the scope
ResultHandle<int> result1 = scope.Add(async token => {
   await Task.Delay(TimeSpan.FromMilliseconds(10), token);
   return 1; 
});
ResultHandle<string> result2 = scope.Add(async token => {
   await Task.Delay(TimeSpan.FromMilliseconds(10), token);
   return "2"; 
});
// run all tasks
RunToken result = await scope.Run();
// and access their values
int value1 = result1.Value(result);
string value2 = result2.Value(result);
