Method: Mechanize::HTTP::Agent#content_encoding_zstd

Defined in:
lib/mechanize/http/agent.rb

#content_encoding_zstd(body_io) ⇒ Object

Decodes a Zstd-encoded body_io

(Experimental, CRuby only) Although Mechanize will never request a zstd-encoded response via accept-encoding, buggy servers may return zstd-encoded responses, or you might need to inform the zstd keyword on your Accept-Encoding headers. Let’s try to handle those cases if the Zstd gem is loaded.

If you need to handle Zstd-encoded responses, install the ‘zstd-ruby’ gem and require it in your application. If the Zstd constant is defined, Mechanize will attempt to use it to inflate the response.
