# List::Objects::WithUtils::Hash::Immutable::Typed(3pm)

Immutable typed hashes

## NAME

List::Objects::WithUtils::Hash::Immutable::Typed - Immutable typed hashes

## SYNOPSIS

```
  use List::Objects::WithUtils 'immhash_of';
  use Types::Standard -types;
  my $hash = immhash_of Int() => ( foo => 1, bar => 2 );
```

## DESCRIPTION

These are immutable type-checking hash objects, essentially a combination of List::Objects::WithUtils::Hash::Typed and List::Objects::WithUtils::Hash::Immutable.

Type-checking is performed when the object is created; attempts to modify the object will throw an exception.

This class consumes the following roles, which contain most of the relevant documentation:

List::Objects::WithUtils::Role::Hash

List::Objects::WithUtils::Role::Hash::Typed

List::Objects::WithUtils::Role::Hash::Immutable

### immhash\_of

Creates a new immutable typed hash object.
