NAME

       List::Objects::WithUtils::Role::Hash::Typed - Type-checking hash behavior

SYNOPSIS

         # Via List::Objects::WithUtils::Hash::Typed ->
         use List::Objects::WithUtils 'hash_of';
         use Types::Standard -all;

         my $arr = hash_of(Int, foo => 1, bar => 2);
         $arr->set(baz => 3.14159);    # dies, failed type check

DESCRIPTION

       This role makes use of Type::Tie to add type-checking behavior to
       List::Objects::WithUtils::Role::Hash consumers.

       The first argument passed to the constructor should be a Type::Tiny type (or other object
       conforming to Type::API, as of "v2.25"):

         use Types::Standard -all;
         my $arr = hash_of ArrayRef() => (foo => [], bar => []);

       Values are checked against the specified type when the object is constructed or new
       elements are added.

       If the initial type-check fails, a coercion is attempted.

       Values that cannot be coerced will throw an exception.

       Also see Types::Standard, List::Objects::Types

   type
       Returns the Type::Tiny type the object was created with.

   untyped
       Returns a (shallow) clone that is a plain List::Objects::WithUtils::Hash.
