SYNOPSIS
This object is used indirectly via the "IO::Async::Loop"'s "detach_code" method.
use IO::Async::Loop;
my $loop = IO::Async::Loop->new;
my $code = $loop->detach_code(
code => sub {
my ( $number ) = @_;
return is_prime( $number );
}
);
$code->call(
args => [ 123454321 ],
on_return => sub {
my $isprime = shift;
print "123454321 " . ( $isprime ? "is" : "is not" ) . " a prime number\n";
},
on_error => sub {
print STDERR "Cannot determine if it's prime - $_[0]\n";
},
);
$loop->run;
DESCRIPTION
This object class provides a legacy compatibility layer for existing code that tries to construct such an object. It should not be used for new code; see instead the IO::Async::Function object, for which this is now a wrapper.CONSTRUCTOR
$code = $loop->detach_code( %params )
This function returns a new instance of a "IO::Async::DetachedCode" object. The %params hash takes the following keys:- code => CODE
- A block of code to call in the child process.
- stream
- marshaller
- These arguments are no longer used; any values passed will be ignored.
- workers => INT
-
Optional integer, specifies the number of parallel workers to create.
If not supplied, 1 is used.
- exit_on_die => BOOL
- setup => ARRAY
- Passed through to the underlying "IO::Async::Function" object.
