Exporter::Tiny::Manual::Etc(3)             User Contributed Perl Documentation


NAME
       Exporter::Tiny::Manual::Etc - odds and ends

DESCRIPTION
   Utility Functions
       Exporter::Tiny is itself an exporter!

       These functions are really for internal use, but can be exported if you
       need them:

       mkopt(\@array)
           Similar to "mkopt" from Data::OptList. It doesn't support all the
           fancy options that Data::OptList does ("moniker", "require_unique",
           "must_be" and "name_test") but runs about 50% faster.

       mkopt_hash(\@array)
           Similar to "mkopt_hash" from Data::OptList. See also "mkopt".

   History
       Type::Library had a bunch of custom exporting code which poked coderefs
       into its caller's stash. It needed this to be something more powerful
       than most exporters so that it could switch between exporting Moose,
       Mouse and Moo-compatible objects on request. Sub::Exporter would have
       been capable, but had too many dependencies for the Type::Tiny project.

       Meanwhile Type::Utils, Types::TypeTiny and Test::TypeTiny each used the
       venerable Exporter.pm. However, this meant they were unable to use the
       features like Sub::Exporter-style function renaming which I'd built
       into Type::Library:

          ## import "Str" but rename it to "String".
          use Types::Standard "Str" => { -as => "String" };

       And so I decided to factor out code that could be shared by all Type-
       Tiny's exporters into a single place: Exporter::TypeTiny.

       As of version 0.026, Exporter::TypeTiny was also made available as
       Exporter::Tiny, distributed independently on CPAN. CHOCOLATEBOY had
       convinced me that it was mature enough to live a life of its own.

       As of version 0.030, Type-Tiny depends on Exporter::Tiny and
       Exporter::TypeTiny is being phased out.

   Obligatory Exporter Comparison
       Exporting is unlikely to be your application's performance bottleneck,
       but nonetheless here are some comparisons.

       Comparative sizes according to Devel::SizeMe:

          Exporter                     217.1Kb
          Sub::Exporter::Progressive   263.2Kb
          Exporter::Tiny               267.7Kb
          Exporter + Exporter::Heavy   281.5Kb
          Exporter::Renaming           406.2Kb
          Sub::Exporter                701.0Kb

       Performance exporting a single sub:

                     Rate     SubExp    ExpTiny SubExpProg      ExpPM
       SubExp      2489/s         --       -56%       -85%       -88%
       ExpTiny     5635/s       126%         --       -67%       -72%
       SubExpProg 16905/s       579%       200%         --       -16%
       ExpPM      20097/s       707%       257%        19%         --

       (Exporter::Renaming globally changes the behaviour of Exporter.pm, so
       could not be included in the same benchmarks.)

       (Non-Core) Dependencies:
