The Pro package is entirely separate from Oban itself. We used to colocate Pro guides with the regular hexdocs, but it was impossible to display module docs with types, functions, etc. Since then Pro, Web, and Met have their own dedicated docs with guides and module docs.

All of the Pro module docs are available through the MODULES sidebar navigation where they’re organized into engines, extensions, plugins, and workers.

The perform/1 callback is defined in the OSS Oban.Worker. All Pro workers use process/1 instead, as defined in Oban.Pro.Worker. There’s a section about migrating to process/1 in the Adoption Guide.

Take a look at Oban.Pro.Worker

That’s because it’s only defined for Oban.Pro.Worker in the oban_pro docs, not the oban hexdocs. Sorry, as configurable as ex_doc is, the docs can’t be colocated.
