Fiber

Fiber allows concurrent execution of code.

Fiber.wait

Takes in duration in milliseconds and returns a future that resolved after the duration.

Signature

-> Number ms : Unawaited<Null>

Example

# before 1 second
Future.wait(1000).await;
# after 1 second

Fiber.runConcurrently

Takes in a list of functions that returns the list of values returned.

Signature

-> List<Any> functions : Unawaited<List<Any>>

Example

results := Fiber.runConcurrently([
    -> : {
        Fiver.wait(1000);
        return "Hello";
    },
    -> : {
        Fiver.wait(3000);
        return "World";
    },
    -> : {
        Fiver.wait(2000);
        return "!";
    },
]).await;

# this takes only around 3-4 seconds
# prints ["Hello", "World", "!"]
print(results);
