AsyncK provides Async, await, beginAsync and suspendAsync which are compatible with ones in this proposal.
The following code written with async/await
func foo() async -> Int {
return suspendAsync { continuation in
// ...
}
}
func bar(_ x: Int) async -> Int {
// ...
}
beginAsync {
let a = await foo()
let b = await bar(a)
print(b)
}can be rewritten as follows:
func foo() -> Async<Int> {
return suspendAsync { continuation in
// ...
}
}
func bar(_ x: Int) -> Async<Int> {
// ...
}
beginAsync {
foo().await { a in
bar(a).await { b -> Void in
print(b)
}
}
}It is also possible to flatten the nest inside the beginAsync's trailing closure.
foo().await { a in
bar(a)
}.await { b -> Void in
print(b)
}MIT
