Overview

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

Rust parses the source, walks every array literal (replicating the ‘each_argument_node` / `ignore_node` claiming of arrays by a method call’s left parenthesis), decides the alignment base for the configured ‘EnforcedStyle` (bracket / after-paren / parent hash key / start of line) and returns each misindented first element and hanging right bracket as an offense range plus its `column_delta` and message. Ruby supplies the flattened config and applies the realignment via `AlignmentCorrector` (the same division of labour as the other alignment cops). 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, enforce_fixed_indentation]`. The enforce flag replicates `enforce_first_argument_with_fixed_indentation?`: the cop stands down (except in `consistent` style) when `Layout/ArrayAlignment` enforces `with_fixed_indentation`.
