Overview

Drop-in Rust reimplementation of Lint/UselessAccessModifier.

Rust walks the AST once and replicates the union of stock's entry points: the check_node handlers on class/module/sclass bodies and eval-style / included blocks, the check_scope recursion that tracks cur_vis/unused through transparent children (conditionals, begin bodies, plain blocks, hash values…) while skipping method definitions and defs, and the unconditional top-level on_begin flagging — including the macro? scope chain that gates bare_access_modifier? and the private_class_method-with-arguments state reset. Offense ranges (the modifier send) and modifier names come from Rust; Ruby formats stock's message and derives the whole-line removal with the stock range_by_whole_lines helper, so the autocorrect is byte-identical by construction. Offenses come from the per-file bundled run (Shirobai::Dispatch); the config is two string lists (ContextCreatingMethods / MethodCreatingMethods) plus the ActiveSupportExtensionsEnabled flag, so this cop is always bundle-eligible.
