I know it's imposible.
is there's a way if i want to create an interface that have
method with return type value is equals with return type of
std.palallelism.task
eg.
interface IWorker{
auto activate(); //on implementation class activate return
std.parallelism.task
}
What is the replacement of auto on that interface?
Thank you!
You want to use ReturnType from std.traits.
task() is a template function so you have to define its template
params or do a template interface, i guess.
#1:
void f() {
}
interface IWorker{
ReturnType!(task!f) activate(); //on implementation class
activate return std.parallelism.task
}
#2:
interface IWorker(T, Args...){
ReturnType!(task!(T, Args)) activate(); //on implementation
class activate return std.parallelism.task
}
