NAME

Mojo::Promise::Role::Any - Fulfill with the first fulfilled promise

SYNOPSIS

use Mojo::Promise;

my $any_promise = Mojo::Promise
	->with_roles( '+Any' )
	->any( @promises );

DESCRIPTION

Make a new promise that fulfills with the first fulfilled promise, and rejects otherwise. The result is a flat list of the arguments for the fulfilled promise (and not an anonymous array of values).

This should be the Perl expression of the same idea in bluebirdjs (http://bluebirdjs.com/docs/api/promise.any.html).

This is handy, for instance, for asking for several servers to provide the same resource and taking the first one that responds.

any( @promises )

Takes a lists of promises (or thenables) and returns another promise that fulfills when any promise fulfills (and it ignores the others after that).

If none of the promises fulfill, the any promise rejects.

If you pass no promises, the any promise rejects.
