Overview

Identifier of all cops containing a department and cop name.

All cops are identified by their badge. For example, the badge for `RuboCop::Cop::Layout::IndentationStyle` is `Layout/IndentationStyle`. Badges can be parsed as either `Department/CopName` or just `CopName` to allow for badge references in source files that omit the department for RuboCop to infer.
