Overview

Drop-in Rust reimplementation of Layout/AccessModifierIndentation.

Rust walks the AST once, reproducing stock's on_class / on_sclass / on_module / on_block alias chain: for every class-like / block node, look at the body and — when it is a parser-(begin ...) (>= 2 statements; prism's single-statement StatementsNode mirrors stock's bare body so we skip it) — inspect each direct child send that is a bare_access_modifier? (no receiver / no arguments / no block, name in {public, protected, private, module_function}). Same-line modifiers (same_line?(node, modifier)) are skipped, exactly like stock. For each kept modifier Rust returns column_delta = expected - actual (matching stock's @column_delta in column_offset_between(modifier.source_range, node.loc.end)); the wrapper either fires correct_style_detected (delta zero) or registers the offense and shifts the modifier's line by column_delta (mirroring stock's AlignmentCorrector.correct(corrector, processed_source, node, column_delta) for a one-line node, which simply inserts or removes leading whitespace).

Stock's AlignmentCorrector.correct reads processed_source.config (for using_tabs?); a faithful drop-in does the same — autocorrect is skipped entirely under Layout/IndentationStyle: tabs, just like stock.

Offenses come from the per-file bundled run (Shirobai::Dispatch); the behaviour is purely config-driven (EnforcedStyle + a per-cop or global IndentationWidth), so this cop is always bundle eligible.

.bundle_args(config) ⇒ Object

Packed args for the bundled run: [style, indentation_width]. indentation_width mirrors Alignment#configured_indentation_width — the cop's own IndentationWidth if set, else Layout/IndentationWidth's Width, else 2.
