Role::HasPayload::Auto - a thing that automatically computes its payload based on attributes
version 0.006
package Example; use Moose; with qw(Role::HasPayload::Auto); sub Payload { 'Role::HasPayload::Meta::Attribute::Payload' } has height => ( is => 'ro', traits => [ Payload ], ); has width => ( is => 'ro', traits => [ Payload ], ); has color => ( is => 'ro', );
...then...
my $example = Example->new({ height => 10, width => 20, color => 'blue', }); $example->payload; # { height => 10, width => 20 }
Role::HasPayload::Auto only provides one method, payload, which returns a hashref of the name and value of every attribute on the object with the Role::HasPayload::Meta::Attribute::Payload trait. (The attribute value is gotten with the the method returned by the attribute's get_read_method method.)
payload
get_read_method
This role is especially useful when combined with Role::HasMessage::Errf.
