Types::...ArrayRef(3)

✨ NAME ✨

okay bestie, welcome to the manual page for Types::Standard::ArrayRef — the exporter utility for the ArrayRef type constraint. The man page title situation is Types::...ArrayRef(3), and this is a User Contributed Perl Documentation page, iykyk. 💅

🎀 SYNOPSIS 🎀

Lowkey the quickest way to get the vibe:

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. periodt.

🦋 DESCRIPTION 🦋

This is mostly internal code, but it can also act as an exporter utility. So like, it’s lowkey a behind-the-scenes helper that can also show up to the group chat and export stuff for you. 💖

🎀 Exports 🎀

Types::Standard::ArrayRef can be used experimentally as an exporter. Obsessed with a lil experiment.

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 { ... } };
