extract_and_augment_context {lambdr} | R Documentation |
Combine class-specific context with general context for an event
Description
The extract_context
function dispatches on the class of an
event to extract context specific to that class. By default, it returns an
empty list. This function takes that class-specific context and combined it
with the context that is applicable for all classes, contained in both
event headers and environment variables.
Usage
extract_and_augment_context(event, config, ...)
Arguments
event |
the response received from querying the next invocation endpoint. |
config |
A list of configuration values as created by the
|
... |
additional arguments passed to |
Value
list
Event context
Context is metadata associated with each invocation. If the handler function
accepts a context
argument then it will automatically receive at runtime a
named list consisting of these values along with the arguments in the body
(if any). For example, a function such as my_func(x, context)
will receive
the context argument automatically. The context
argument must be named
(...
will not work).
