Produces the description of a processor from it's blueprint description. The information provided by this module correspond to the VacEngine.Pub.info_cached/1 function and the GET info API endpoint.

The info provided includes input, output and logic of the processor:

{:ok, %Info{input: input_schema, output: output_schema, logic: logic}} =
  Info.describe(blueprint)

Input schema

The Json Schema representation of the input accepted by the processor (see: https://json-schema.org/).

Output schema

The Json Schema representation of the output returned by the processor.

Logic description

The logic description gives an overview of the logic involved in the processor. It is by no mean a full description of the processor behaviour. It is more a description of the way certain variables chosen by the editor are deduced.

Technically, a deduction description is provided only if the editor added a description to the assignments of this variable (see VacEngine.Processor documentation for more information about assignments).

Logic description appear as a 3 layers structure: a map keyed by variable names, whose values are maps keyes by possible values, each containing a list the descriptions gathered from the assignments.
