#NAME

Types::Standard::HashRef - exporter utility for the HashRef type constraint

#SYNOPSIS

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

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::HashRef can be used experimentally as an exporter.

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

This will export the following functions into your namespace:

#IntHash
#is_IntHash( $value )
#assert_IntHash( $value )
#to_IntHash( $value )

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

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

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