Specio::Constraint::ObjectDoes - A class for constraints which require an object that does a specific role
my $type = Specio::Constraint::ObjectDoes->new(...); print $type->role;
This is a specialized type constraint class for types which require an object that does a specific role.
This class provides all of the same methods as Specio::Constraint::Simple, with a few differences:
parent parameter is ignored if it passed, as it is always set to the
constraint parameters are also ignored. This class provides its own default inline generator subroutine reference.
This class overrides the
message_generator default if none is provided.
Finally, this class requires an additional parameter,
role. This must be a single role name.
Returns the role name passed to the constructor.
