NAME
Sub::Future - concurrency with futures
SYNOPSIS
use Sub::Future;
my $value = future {
# long running computation goes here
return 'result goes here';
};
# do some things that don't require $value
# while $value is calculated in parallel
# use the computation's return value (blocking if necessary)
print "Long computation returned: $value\n";
Exported Subroutines
future $coderef
Starts executing $coderef
in parallel and then returns immediately. The returned value can be used at any time to retrieve the value calculated by $coderef
. If the parallel calculation isn't done, using the value blocks until the value is ready.
Methods
value
Calling this method on the object returned by "future" returns the value calculated by the code block. It's usually not necessary to call this method directly since most operations performed on the object implicitly return the value.
