NAME
    Types::TypeTiny - type constraints used internally by Type::Tiny

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

DESCRIPTION
    Dogfooding.

    This isn't a real Type::Library-based type library; that would involve too much circularity. But
    it exports some type constraints which, while designed for use within Type::Tiny, may be more
    generally useful.

  Types
    *   StringLike

        Accepts strings and objects overloading stringification.

    *   HashLike[`a]

        Accepts hashrefs and objects overloading hashification.

        Since Types::TypeTiny 1.012, may be parameterized with another type constraint like
        HashLike[Int].

    *   ArrayLike[`a]

        Accepts arrayrefs and objects overloading arrayfication.

        Since Types::TypeTiny 1.012, may be parameterized with another type constraint like
        ArrayLike[Int].

    *   CodeLike

        Accepts coderefs and objects overloading codification.

    *   TypeTiny

        Accepts blessed Type::Tiny objects.

    *   _ForeignTypeConstraint

        Any reference which to_TypeTiny recognizes as something that can be coerced to a Type::Tiny
        object.

        Yes, the underscore is included.

  Coercion Functions
    "to_TypeTiny($constraint)"
        Promotes (or "demotes" if you prefer) a Moose::Meta::TypeConstraint object to a Type::Tiny
        object.

        Can also handle Validation::Class objects. Type constraints built from Validation::Class
        objects deliberately *ignore* field filters when they do constraint checking (and go to
        great lengths to do so); using filters for coercion only. (The behaviour of "coerce" if we
        don't do that is just too weird!)

        Can also handle any object providing "check" and "get_message" methods. (This includes
        Mouse::Meta::TypeConstraint objects.) If the object also provides "has_coercion" and
        "coerce" methods, these will be used too.

        Can also handle coderefs (but not blessed coderefs or objects overloading "&{}"). Coderefs
        are expected to return true iff $_ passes the constraint. If $_ fails the type constraint,
        they may either return false, or die with a helpful error message.

  Methods
    These are implemented so that "Types::TypeTiny->meta->get_type($foo)" works, for rough
    compatibility with a real Type::Library type library.

    "meta"
    "type_names"
    "get_type($name)"
    "has_type($name)"
    "coercion_names"
    "get_coercion($name)"
    "has_coercion($name)"
