Types::Standard::ArrayRef(3)               User Contributed Perl Documentation


NAME
       Types::Standard::ArrayRef - exporter utility for the ArrayRef type
       constraint

SYNOPSIS
         use Types::Standard -types;

         # Normal way to validate an arrayref of integers.
         #
         ArrayRef->of( Int )->assert_valid( [ 1, 2, 3 ] );

         use Types::Standard::ArrayRef Ints => { of => Int },

         # Exported shortcut
         #
         assert_Ints [ 1, 2, 3 ];

STATUS
       This module is not covered by the Type-Tiny stability policy.

DESCRIPTION
       This is mostly internal code, but can also act as an exporter utility.

   Exports
       Types::Standard::ArrayRef can be used experimentally as an exporter.

         use Types::Standard 'Int';
         use Types::Standard::ArrayRef Ints => { of => Int };

       This will export the following functions into your namespace:

       "Ints"
       is_Ints( $value )
       assert_Ints( $value )
       to_Ints( $value )

       Multiple types can be exported at once:

         use Types::Standard -types;
         use Types::Standard::ArrayRef (
           Ints   => { of => Int },
           Nums   => { of => Num },
           Strs   => { of => Str },
         );

         assert_Ints [ 1, 2, 3 ];   # should not die

       It's possible to further constrain the arrayref using "where":

         use Types::Standard::ArrayRef Ints => { of => Int, where => sub { ... } };
