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"
           Accepts hashrefs and objects overloading hashification.

       "ArrayLike"
           Accepts arrayrefs and objects overloading arrayfication.

       "CodeLike"
           Accepts coderefs and objects overloading codification.

       "TypeTiny"
           Accepts blessed Type::Tiny objects.

   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)"
