=head1 NAME

MooseX::Types::Tied::Hash::IxHash - Moose type library for Tie::IxHash tied hashes

=head1 VERSION

This document describes version 0.003 of MooseX::Types::Tied::Hash::IxHash - released April 21, 2012 as part of MooseX-Types-Tied.

=head1 SYNOPSIS

    use Moose;
    use MooseX::Types::Tied::Hash::IxHash ':all';

    has tied_array => (is => 'ro', isa => IxHash);

    # etc...

=head1 DESCRIPTION

This is a collection of L<Moose> types and coercion settings for L<Tie::IxHash>
tied hashes.

The package behaves as you'd expect a L<MooseX::Types> library to act: either
specify the types you want imported explicitly or use the ':all' catchall.

=for stopwords TiedArray TiedHash TiedHandle IxHash

=head1 TYPES

=head2 IxHash

Base type: TiedHash

This type coerces from ArrayRef.  As of 0.004 we no longer coerce from
HashRef, as that lead to 1) annoyingly easy to miss errors involving expecting
C<$thing->attribute( { a => 1, b => 2, ... } )> to result in proper ordering;
and 2) the Hash native trait appearing to work normally but instead silently
destroying the preserved order (during certain write operations).

=head1 WARNING!

This type is not compatible with the write operations allowed by the Hash
Moose native attribute trait.
