NAME

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

STATUS

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

DESCRIPTION

12       Dogfooding.
13
14       This isn't a real Type::Library-based type library; that would involve
15       too much circularity. But it exports some type constraints which, while
16       designed for use within Type::Tiny, may be more generally useful.
17
18   Types
19       "StringLike"
20           Accepts strings and objects overloading stringification.
21
22       "HashLike"
23           Accepts hashrefs and objects overloading hashification.
24
25       "ArrayLike"
26           Accepts arrayrefs and objects overloading arrayfication.
27
28       "CodeLike"
29           Accepts coderefs and objects overloading codification.
30
31       "TypeTiny"
32           Accepts blessed Type::Tiny objects.
33
34   Coercion Functions
35       "to_TypeTiny($constraint)"
36           Promotes (or "demotes" if you prefer) a Moose::Meta::TypeConstraint
37           object to a Type::Tiny object.
38
39           Can also handle Validation::Class objects. Type constraints built
40           from Validation::Class objects deliberately ignore field filters
41           when they do constraint checking (and go to great lengths to do
42           so); using filters for coercion only. (The behaviour of "coerce" if
43           we don't do that is just too weird!)
44
45           Can also handle any object providing "check" and "get_message"
46           methods.  (This includes Mouse::Meta::TypeConstraint objects.) If
47           the object also provides "has_coercion" and "coerce" methods, these
48           will be used too.
49
50           Can also handle coderefs (but not blessed coderefs or objects
51           overloading "&{}"). Coderefs are expected to return true iff $_
52           passes the constraint. If $_ fails the type constraint, they may
53           either return false, or die with a helpful error message.
54
55   Methods
56       These are implemented so that "Types::TypeTiny->meta->get_type($foo)"
57       works, for rough compatibility with a real Type::Library type library.
58
59       "meta"
60       "type_names"
61       "get_type($name)"
62       "has_type($name)"
63       "coercion_names"
64       "get_coercion($name)"
65       "has_coercion($name)"
66
