=head1 NAME
Promises::Deferred::Mojo - An implementation of Promises in Perl
=head1 VERSION
version 0.99
=head1 SYNOPSIS
use Promises backend => ['Mojo'], qw[ deferred collect ];
# ... everything else is the same
=head1 DESCRIPTION
The "Promise/A+" spec strongly suggests that the callbacks
given to C<then> should be run asynchronously (meaning in the
next turn of the event loop), this module provides support for
doing so using the L<Mojo::IOLoop> module.
Module authors should not care which event loop will be used but
instead should just the Promises module directly:
package MyClass;
use Promises qw(deferred collect);
End users of the module can specify which backend to use at the start of
the application:
use Promises -backend => ['Mojo'];
use MyClass;
B<Note:> If you are using Mojolicious with the L<EV> event loop, then you
should use the L<Promises::Deferred::EV> backend instead.
