Overview

Drop-in Rust reimplementation of Style/HashTransformKeys.

Stock matches four shapes via the HashTransformMethod mixin (each_with_object({}) / Hash[_.map {...}] / _.map{...}.to_h / _.to_h{...}) and emits a sequence of corrector ops that strips Hash[ / ] (or the trailing .to_h), swaps the selector to transform_keys, rewrites the block arguments and replaces the body with just the key transformation. Rust replays the same gating (hash_receiver?, noop_transformation?, transformation_uses_both_args?, use_transformed_argname?) on the prism tree and returns the offense span plus an ordered list of (start, end, replacement) edits the wrapper plays back verbatim via corrector.replace.

.bundle_args(_config) ⇒ Object

Config-less from the bundle's point of view: no per-cop config influences detection or autocorrect. (The cop's Enabled / Exclude / etc. are honoured by the Team, not by us.)
