Package: libtie-hash-indexed-perl (0.08+ds1-1 and others)

Ordered hashes for Perl

This module implements an ordered hash, meaning that it associates keys with values like a Perl hash, but keeps the keys in a consistent order.

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.
