Types::...HashRef(3)

okay so bestie, welcome to the Types::...HashRef(3) page — straight outta User Contributed Perl Documentation. This is lowkey about Types::Standard::HashRef, the exporter utility for the HashRef type constraint. 💅

✨ NAME ✨

Types::Standard::HashRef — an exporter utility for the HashRef type constraint. That's the whole name vibe, no cap. 🫶

🌸 SYNOPSIS 🌸

Bestie, here's the canonical code, untouched, fr fr:

use Types::Standard -types;

# Normal way to validate a hashref of integers.
#
HashRef->of( Int )->assert_valid( { one => 1 } );

use Types::Standard::HashRef IntHash => { of => Int },

# Exported shortcut
#
assert_IntHash { one => 1 };

💀 STATUS 💀

Real talk: This module is not covered by the Type-Tiny stability policy. So like, stability-policy wise? Not covered. Periodt.

🦋 DESCRIPTION 🦋

Mostly internal code, but it can also act as an exporter utility. Main character energy, honestly.

🫶 Exports 🫶

Types::Standard::HashRef can be used experimentally as an exporter. Like, experimentally experimental.

use Types::Standard 'Int';
use Types::Standard::HashRef IntHash => { of => Int };

This will export the following functions into your namespace:

• "IntHash" — on the export list, periodt. 💖
• is_IntHash( $value ) — also exported, no cap. ✨
• assert_IntHash( $value ) — exported too, bestie. 🎀
• to_IntHash( $value ) — yep, this one too. 🦋

Multiple types can be exported at once:

use Types::Standard -types;
use Types::Standard::HashRef (
  IntHash  => { of => Int },
  NumHash  => { of => Num },
  StrHash  => { of => Str },
);

assert_IntHash { two => 2 };   # should not die

The # should not die comment is doing exactly what it says on the tin. 🫶

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

use Types::Standard::HashRef MyThing => { of => Int, where => sub { ... } };
