Breadcrumbs support

[UberMouse]

Support for Rayguns new breadcrumbs feature. Breadcrumbs let you provide logging points in your code that will be collected and sent along with any exception sent to Raygun. This lets you have a better understanding of the events that happened in the system that lead up to the exception.

There are two ways of recording a breadcrumb

1. Include it as a module in your class

class SomeClass
  include Raygun::Breadcrumbs
  
  def some_method
    record_breadcrumb(
      message: "<log message goes here>",
      category: "some category to group them by, maybe authentication or external-apis for example",
      level: :info, # or debug or warning etc, you can configure what level will get sent
      metadata: {custom_data: 'can go here'},
    )
  end
end

This has the added benefit of recording the class the breadcrumb was recorded from automatically

2. Call the record_breadcrumb method manually

def some_method
  Raygun.record_breadcrumb(
    message: "<log message goes here>",
    category: "some category to group them by, maybe authentication or external-apis for example",
    level: :info, # or debug or warning etc, you can configure what level will get sent
    metadata: {custom_data: 'can go here'},
    
    # You can also set the class the breadcrumb was logged from 
    # It will only be set automatically using the included module approach
    # Method and line number will get added automatically
    class_name: self.class.name
  )
end
