NAME

7

STATUS

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

DESCRIPTION

12       Type constraints of the general form "{ $_->can("method") }".
13
14       This package inherits from Type::Tiny; see that for most documentation.
15       Major differences are listed below:
16
17   Attributes
18       "methods"
19           An arrayref of method names.
20
21       "constraint"
22           Unlike Type::Tiny, you cannot pass a constraint coderef to the
23           constructor.  Instead rely on the default.
24
25       "inlined"
26           Unlike Type::Tiny, you cannot pass an inlining coderef to the
27           constructor.  Instead rely on the default.
28
29       "parent"
30           Parent is always Types::Standard::Object, and cannot be passed to
31           the constructor.
32
33   Methods
34       "stringifies_to($constraint)"
35           See Type::Tiny::ConstrainedObject.
36
37       "numifies_to($constraint)"
38           See Type::Tiny::ConstrainedObject.
39
40       "with_attribute_values($attr1 => $constraint1, ...)"
41           See Type::Tiny::ConstrainedObject.
42
43   Exports
44       Type::Tiny::Duck can be used as an exporter.
45
46         use Type::Tiny::Duck HttpClient => [ 'get', 'post' ];
47
48       This will export the following functions into your namespace:
49
50       "HttpClient"
51       "is_HttpClient( $value )"
52       "assert_HttpClient( $value )"
53       "to_HttpClient( $value )"
54
55       Multiple types can be exported at once:
56
57         use Type::Tiny::Duck (
58           HttpClient   => [ 'get', 'post' ],
59           FtpClient    => [ 'upload', 'download' ],
60         );
