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.)
