Types::Standard::HashRef − exporter utility for the HashRef type constraint
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 };
This module is not covered by the Type−Tiny stability policy.
This is mostly internal code, but can also act as an exporter utility.
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 { ... } };
