NAME
Acme::CPANModules::OrderedHash - List of modules that provide ordered
hash data type
VERSION
This document describes version 0.004 of Acme::CPANModules::OrderedHash
(from Perl distribution Acme-CPANModules-OrderedHash), released on
2025-04-15.
SYNOPSIS
To run benchmark with default option:
% bencher --cpanmodules-module OrderedHash
To run module startup overhead benchmark:
% bencher --module-startup --cpanmodules-module OrderedHash
For more options (dump scenario, list/include/exclude/add participants,
list/include/exclude/add datasets, etc), see bencher or run "bencher
--help".
DESCRIPTION
When you ask a Perl's hash for the list of keys, the answer comes back
unordered. In fact, Perl explicitly randomizes the order of keys it
returns everytime. The random ordering is a (security) feature, not a
bug. However, sometimes you want to know the order of insertion. These
modules provide you with an ordered hash; most of them implement it by
recording the order of insertion of keys in an additional array.
Tie::StoredOrderHash
Array::OrdHash
Provide something closest to PHP's associative array, where you can
refer elements by key or by numeric index, and insertion order is
remembered.
List::Unique::DeterministicOrder
Provide a list, not hash.
Tree::RB::XS
Multi-purpose tree data structure which can record insertion order
and act as an ordered hash. Use "track_recent => 1,
keys_in_recent_order => 1" options. Can be used as a tied hash, or
as an object (faster).
BENCHMARKED MODULES
Version numbers shown below are the versions used when running the
sample benchmark.
Tie::IxHash 1.23
(6 cores)*, OS: *GNU/Linux Ubuntu version 24.10*, OS kernel: *Linux
version 6.11.0-8-generic*.
Benchmark command (default options):
% bencher --cpanmodules-module OrderedHash

# ABSTRACT: List of modules that provide ordered hash data type
=head1 DESCRIPTION
This module is automatically generated by Pod::Weaver::Plugin::Bencher::Scenario during distribution build.
A Acme::CPANModules_ScenarioR::* module contains the raw result of sample benchmark and might be useful for some stuffs later.
