Types::Standard::Tuple(3pm)

Usage

  use Types::Standard -types;
  
  # Normal way to validate a pair of integers.
  #
  Tuple->of( Int, Int )->assert_valid( [ 7, 49 ] );
  
  use Types::Standard::Tuple IntPair => { of => [ Int, Int ] },
  
  # Exported shortcut
  #
  assert_IntPair [ 7, 49 ];

Status

This module is not covered by the Type-Tiny stability policy.

Overview

This is mostly internal code, but can also act as an exporter utility.

Exports

Types::Standard::Tuple can be used experimentally as an exporter.

  use Types::Standard 'Int';
  use Types::Standard::Tuple IntPair => { of => [ Int, Int ] };

This will export the following functions into your namespace:

"IntPair"

is_IntPair( $value )

assert_IntPair( $value )

to_IntPair( $value )

Multiple types can be exported at once:

  use Types::Standard -types;
  use Types::Standard::HashRef (
    IntPair  => { of => [ Int, Int ] },
    StrInt   => { of => [ Str, Int ] },
  );
  
  assert_StrInt [ two => 2 ];   # should not die

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

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