NAME

Types::Standard::ArrayRef − exporter utility for the ArrayRef type constraint

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 { ... } };
