Types::Standard::ArrayRef

exporter utility for the ArrayRef type constraint

  use Types::Standard -types;
  
  # Normal way to validate an arrayref of integers.
  #
  ArrayRef->of( Int )->assert_valid( [ 1, 2, 3 ] );
  
  use Types::Standard::ArrayRef Ints => { of => Int },
  
  # Exported shortcut
  #
  assert_Ints [ 1, 2, 3 ];

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::ArrayRef can be used experimentally as an exporter.

  use Types::Standard 'Int';
  use Types::Standard::ArrayRef Ints => { of => Int };

This will export the following functions into your namespace:

"Ints"

Multiple types can be exported at once:

  use Types::Standard -types;
  use Types::Standard::ArrayRef (
    Ints   => { of => Int },
    Nums   => { of => Num },
    Strs   => { of => Str },
  );
  
  assert_Ints [ 1, 2, 3 ];   # should not die

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

  use Types::Standard::ArrayRef Ints => { of => Int, where => sub { ... } };
