NAME

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

SYNOPSIS

            

              
              
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.

DESCRIPTION

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 { ... } };
