//
// So, 'suspend' returns control to the place from which it was
// called (the "call site"). How do we control back to the
// suspended function?
//
// For that, we have a new keyword called 'resume' which takes an
// async function invocation's frame and returns control to it.
//
// fn fooThatSuspends() void {
// suspend;
// }
//
// var foo_frame = async fooThatSuspends();
// resume foo_frame;
//
// See if you can make this program print "Hello async!".
//
const print = @import("std").debug.print;
pub fn main() void {
var foo_frame = async foo();
}
fn foo() void {
print("Hello ", .{});
suspend;
print("async!\n", .{});
}
