Module: Typhoeus::Hydra::Before Private

Included in:
Typhoeus::Hydra
Defined in:
lib/typhoeus/hydra/before.rb

Overview

This module is part of a private API. You should avoid using this module if possible, as it may be removed or be changed in the future.

This module provides a way to hook into before a request gets queued in hydra. This is very powerful and you should be careful because when you accidently return a falsy value the request won’t be executed.

Since:

  • 0.5.0
