Overview

Drop-in Rust reimplementation of ‘Layout/MultilineMethodCallIndentation`.

Rust parses the source, finds ‘.`-chained method calls whose selector is misindented across lines, and returns the offending range, the column delta and the formatted message. Ruby supplies the flattened config (style + indentation widths) and applies the realignment via `AlignmentCorrector` (special-casing calls that carry a multiline block). Offenses come from the per-file bundled run (`Shirobai::Dispatch`); the config derivation is purely config-driven, so this cop is always bundle-eligible.

.bundle_args(config) ⇒ Object

Packed args for the bundled run: ‘[style, indentation_width, base_indentation_width]`. `EnforcedStyle` is absent when the config does not mention this cop (e.g. a spec configures only the sibling multiline cop, and this cop’s offenses are discarded); default to the first supported style (‘0`) in that case.
