HTTP::...s::Fast(3pm)

🌸 NAME 🌸

hey bestie 💖 welcome to the HTTP::...s::Fast(3pm) page — yes, User Contributed Perl Documentation, we're in it. the main character is HTTP::Headers::Fast, and it's a faster implementation of HTTP::Headers 💅

✨ SYNOPSIS ✨

okay so the whole synopsis is literally this:

use HTTP::Headers::Fast;
# and, same as HTTP::Headers.

💖 DESCRIPTION 💖

HTTP::Headers::Fast is a perl class for parsing/writing HTTP headers. The interface is same as HTTP::Headers — cute, consistent, no cap ✨

🦋 WHY YET ANOTHER ONE? 🦋

so why yet another one? HTTP::Headers is a very good. But I needed a faster implementation, fast =)

🎀 ADDITIONAL METHODS 🎀

these are the extra methods, and yes they are iconic 💅

as_string_without_sort

as_string sorts the header names. But sorting is a bit slow.

This method stringifies the instance of HTTP::Headers::Fast without sorting.

psgi_flatten

returns a PSGI compatible arrayref of header.

the original snippet goes like this:

my $headers:ArrayRef = $header->flatten

psgi_flatten_without_sort

same as flatten but returns an arrayref without sorting.

🔥 @ISA HACK 🔥

If you want HTTP::Headers::Fast to pretend like it's really HTTP::Headers, you can try the following hack:

unshift @HTTP::Headers::Fast::ISA, 'HTTP::Headers';

👑 BENCHMARK 👑

okay benchmark time, the stats are HTTP::Headers 5.818, HTTP::Headers::Fast 0.01, and I'm keeping every number exactly as given, no cap:
