=head1 DESCRIPTION |
34
|
|
|
|
|
|
35
|
|
|
|
|
These are type-checking hash objects; values are checked against the specified |
36
|
|
|
|
|
type when the object is constructed or new elements are added. |
37
|
|
|
|
|
|
38
|
|
|
|
|
The first argument passed to the constructor should be a L<Type::Tiny> type: |
39
|
|
|
|
|
|
40
|
|
|
|
|
use Types::Standard -all; |
41
|
|
|
|
|
my $hash = hash_of Int() => ( foo => 1 ); |
42
|
|
|
|
|
|
43
|
|
|
|
|
If the initial type-check fails, a coercion is attempted. |
