Overview

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

Rust parses the source, walks every method call with arguments, decides the alignment base for the configured ‘EnforcedStyle`, and returns the first argument as an offense range plus its `column_delta`, the message, the `within?` autocorrect flag and the range to realign (which for `special_for_inner_method_call_in_parentheses` may be the whole receiver chain). 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_with_no_line_break]`. The enforce flag replicates the instance derivation: `Layout/ArgumentAlignment` enforcing `with_fixed_indentation` while `Layout/FirstMethodArgumentLineBreak` is disabled.
