Types::Standard::CycleTuple(3pm)

NAME
Types::Standard::CycleTuple - exporter utility for the CycleTuple type constraint

SYNOPSIS
  use Types::Standard -types;

  # Normal way to validate a list of pairs of integers.
  #
  CycleTuple->of( Int, Int )->assert_valid( [ 7, 49, 8, 64 ] );

  use Types::Standard::CycleTuple IntPairs => { of => [ Int, Int ] },

  # Exported shortcut
  #
  assert_IntPairs [ 7, 49, 8, 64 ];

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::CycleTuple can be used experimentally as an exporter.

  use Types::Standard 'Int';
  use Types::Standard::CycleTuple IntPairs => { of => [ Int, Int ] };

This will export the following functions into your namespace:

"IntPairs"
is_IntPairs( $value )
assert_IntPairs( $value )
to_IntPairs( $value )

Multiple types can be exported at once:

  use Types::Standard -types;
  use Types::Standard::CycleTuple (
    IntIntPairs   => { of => [ Int, Int ] },
    StrIntPairs   => { of => [ Str, Int ] },
  );

  assert_StrIntPairs [ one => 1, two => 2 ];   # should not die

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

  use Types::Standard::CycleTuple MyThing => { of => [ ... ], where => sub { ... } };
