ballerina/lang.future Ballerina library

Requests cancellation of a future.

This sets the cancellation flag in the strand corresponding to f. Each time that a strand yields, it will check the cancellation flag and terminate abnormally if the flag is set.

future<int> sumFuture = start int:sum(10, 13, 54, 245, 24, 29, 343, 34);
sumFuture.cancel();
