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".
