Defined in:

Overview

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

Ensures that BeginRescueEnsure isn’t exposed directly. This function is passed in when #error_handler is called, like this:

error_handler do |t|
  t.begin { "This is the begin" }
  t.rescue(Exception) { "This is the rescue" }
  t.ensure { trace << t.begin_task }
end

In this example, t is a BeginRescueEnsureWrapper which passes the begin/rescue/ensure calls to the BeginRescueEnsure class itself.

#begin(&block) ⇒ Object

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

Binds the block to a lambda to be called when we get to the begin part of the data flow analysis.

Parameters:

  • block —

    The code block to be called when asynchronous begin starts.
