Event and Breadcrumb
hints are objects containing various information used to put together an event or a breadcrumb. These hints are passed as the
hint parameter to
before_breadcrumb (as well as event processors) as a dictionary. More than one hint can be supplied, but this is rare.
If you set this hint, then it's an exc info tuple in the form
(exc_type, exc_value, tb). This can be used to extract additional information from the original error object.
This hint is passed to breadcrumbs and contains the log record that created it. It can be used to extract additional information from the original
logging log record that is not extracted by default. Likewise, it can be useful to discard uninteresting breadcrumbs.
