## NAME
    [Type::Tiny::Intersection](https://www.chedong.com/phpMan.php/perldoc/Type%3A%3ATiny%3A%3AIntersection/markdown) - intersection type constraints

## STATUS
    This module is covered by the Type-Tiny stability policy.

## DESCRIPTION
    Intersection type constraints.

    This package inherits from [Type::Tiny](https://www.chedong.com/phpMan.php/perldoc/Type%3A%3ATiny/markdown); see that for most documentation. Major differences are
    listed below:

### Attributes
    "type_constraints"
        Arrayref of type constraints.

        When passed to the constructor, if any of the type constraints in the intersection is itself
        an intersection type constraint, this is "exploded" into the new intersection.

    "constraint"
        Unlike [Type::Tiny](https://www.chedong.com/phpMan.php/perldoc/Type%3A%3ATiny/markdown), you *cannot* pass a constraint coderef to the constructor. Instead rely
        on the default.

    "inlined"
        Unlike [Type::Tiny](https://www.chedong.com/phpMan.php/perldoc/Type%3A%3ATiny/markdown), you *cannot* pass an inlining coderef to the constructor. Instead rely on
        the default.

    "parent"
        Unlike [Type::Tiny](https://www.chedong.com/phpMan.php/perldoc/Type%3A%3ATiny/markdown), you *cannot* pass an inlining coderef to the constructor. A parent will
        instead be automatically calculated.

        (Technically any of the types in the intersection could be treated as a parent type; we
        choose the first arbitrarily.)

### Methods
    "stringifies_to($constraint)"
        See [Type::Tiny::ConstrainedObject](https://www.chedong.com/phpMan.php/perldoc/Type%3A%3ATiny%3A%3AConstrainedObject/markdown).

    "numifies_to($constraint)"
        See [Type::Tiny::ConstrainedObject](https://www.chedong.com/phpMan.php/perldoc/Type%3A%3ATiny%3A%3AConstrainedObject/markdown).

    "with_attribute_values($attr1 => $constraint1, ...)"
        See [Type::Tiny::ConstrainedObject](https://www.chedong.com/phpMan.php/perldoc/Type%3A%3ATiny%3A%3AConstrainedObject/markdown).

### Overloading
    *   Arrayrefification calls "type_constraints".
