NAME

Types::Set - Set::Equivalence-related type constraints

SYNOPSIS

   package Band {
      use Moose;
      use Types::Standard qw( InstanceOf );
      use Types::Set qw( Set );
      
      has members => (
         is          => 'ro',
         isa         => Set[ InstanceOf['Person'] ],
         coerce      => 1,
         default     => sub { +[] },
         handles     => {
            add_member     => 'insert',
            has_member     => 'contains',
            member_count   => 'size',
         }
      );
   }

DESCRIPTION

Types::Set is a type constraint library built using Type::Tiny; compatible with Moose, Mouse, Moo and more.

Type constraints

AnySet

This type constraint is satisfied by any blessed object that provides insert, delete, members and contains methods.

Set

A blessed Set::Equivalence object.

This may be parameterized with another type constraint; for example, Set[Num] is a set of numbers. In this case, not only must all the set members be numbers, but also the set itself must have a type constraint of Num (or a subtype of Num, such as Int) attached, which will prevent non-numeric values from being inserted into the set later.

This type can coerce from ArrayRef and AnySet.

MutableSet

Like Set, but must be a mutable set. Similar parameterization.

This type can coerce from ImmutableSet, ArrayRef and AnySet.

ImmutableSet

Like Set, but must not be a mutable set. Similar parameterization.

This type can coerce from MutableSet, ArrayRef and AnySet.
