Ordered hashes for Perl
Tie::Hash::Indexed is intentionally very similar to other ordered hash modules, most prominently Hash::Ordered. However, Tie::Hash::Indexed is written completely in XS and is, often significantly, faster than other modules. For a lot of operations, it's more than twice as fast as Hash::Ordered, especially when using the object-oriented interface instead of the tied interface. Other modules, for example Tie::IxHash, are even slower.
The object-oriented interface of Tie::Hash::Indexed is almost identical to that of Hash::Ordered, so in most cases you should be able to easily replace one with the other.
Installation of the Tie::Hash::Indexed module follows the standard Perl Way and should not be harder than:
perl Makefile.PL
make
make test
make install
Note that you may need to become superuser to make install.
If you're building the module under Windows, you may need to use a
different make program, such as nmake, instead of make.
You can enable or disable certain features at compile time by adding
options to the Makefile.PL call. However, you can safely leave them
at their default.
Currently, the only available feature is debug to build the module
with debugging support. If your perl binary was already built with
debugging support, the debug feature is enabled by default.
You can enable or disable features explicitly by adding the arguments
enable-feature
disable-feature
to the Makefile.PL call. To explicitly build the module with debugging
enabled, you would say:
perl Makefile.PL enable-debug
This will still allow you to pass other standard arguments to
Makefile.PL, like
perl Makefile.PL enable-debug OPTIMIZE=-O3
