NAME

       Type::Tiny::Union - union type constraints

STATUS

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

DESCRIPTION

       Union type constraints.

       This package inherits from Type::Tiny; see that for most documentation.  Major differences
       are listed below:

   Constructor
       The "new" constructor from Type::Tiny still works, of course. But there is also:

       "new_by_overload(%attributes)"
           Like the "new" constructor, but will sometimes return another type constraint which is
           not strictly an instance of Type::Tiny::Union, but still encapsulates the same
           meaning. This constructor is used by Type::Tiny's overloading of the "|" operator.

   Attributes
       "type_constraints"
           Arrayref of type constraints.

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

       "constraint"
           Unlike Type::Tiny, you cannot pass a constraint coderef to the constructor.  Instead
           rely on the default.

       "inlined"
           Unlike Type::Tiny, you cannot pass an inlining coderef to the constructor.  Instead
           rely on the default.

       "parent"
           Unlike Type::Tiny, you cannot pass an inlining coderef to the constructor.  A parent
           will instead be automatically calculated.

       "coercion"
           You probably do not pass this to the constructor. (It's not currently disallowed, as
           there may be a use for it that I haven't thought of.)

           The auto-generated default will be a Type::Coercion::Union object.

   Methods
       "find_type_for($value)"
           Returns the first individual type constraint in the union which $value passes.

       "stringifies_to($constraint)"
           See Type::Tiny::ConstrainedObject.

       "numifies_to($constraint)"
           See Type::Tiny::ConstrainedObject.

       "with_attribute_values($attr1 => $constraint1, ...)"
           See Type::Tiny::ConstrainedObject.

   Overloading
       •   Arrayrefification calls "type_constraints".
