NAME
    Moose::Meta::TypeConstraint::Role - Role/TypeConstraint parallel hierarchy

VERSION
    version 2.2200

DESCRIPTION
    This class represents type constraints for a role.

INHERITANCE
    "Moose::Meta::TypeConstraint::Role" is a subclass of Moose::Meta::TypeConstraint.

METHODS
  Moose::Meta::TypeConstraint::Role->new(%options)
    This creates a new role type constraint based on the given %options.

    It takes the same options as its parent, with two exceptions. First, it requires an additional
    option, "role", which is name of the constraint's role. Second, it automatically sets the parent
    to the "Object" type.

    The constructor also overrides the hand optimized type constraint with one it creates
    internally.

  $constraint->role
    Returns the role name associated with the constraint.

  $constraint->parents
    Returns all the type's parent types, corresponding to the roles that its role does.

  $constraint->is_subtype_of($type_name_or_object)
    If the given type is also a role type, then this checks that the type's role does the other
    type's role.

    Otherwise it falls back to the implementation in Moose::Meta::TypeConstraint.

  $constraint->create_child_type(%options)
    This returns a new Moose::Meta::TypeConstraint object with the type as its parent.

    Note that it does *not* return a "Moose::Meta::TypeConstraint::Role" object!
