NAME

Promise::XS::Promise - promise object

SYNOPSIS

See Promise::XS.

DESCRIPTION

This is Promise::XS’s actual promise object class. It implements these methods:

• then()

• catch()

• finally()

… which behave as they normally do in promise implementations.

Additionally, all() and race() may be used, thus:

            

              
              
my $p3 = Promise::XS::Promise->all( $p1, $p2, .. );
my $p3 = Promise::XS::Promise->race( $p1, $p2, .. );
            
          

… or, just:

            

              
              
my $p3 = ref($p1)->all( $p1, $p2, .. );
my $p3 = ref($p1)->race( $p1, $p2, .. );
            
          

… or even:

            

              
              
my $p3 = $p1->all( $p1, $p2, .. );
my $p3 = $p1->race( $p1, $p2, .. );
            
          

(Note the repetition of $p1 in these last examples!)

NOTES

Subclassing this class won’t work because the above-named methods always return instances of (exactly) this class. That may change eventually, but for now this is what’s what.
