Overview

Drop-in Rust reimplementation of Layout/FirstHashElementIndentation.

Rust parses the source, walks every braced hash literal (replicating the each_argument_node / ignore_node claiming of hashes by a method call's left parenthesis), decides the alignment base for the configured EnforcedStyle (brace / after-paren / parent hash key / start of line), applies the Layout/HashAlignment separator longest-key offset when configured, and returns each misindented first pair and hanging right brace as an offense range plus its column_delta, message and an autocorrect-target marker. Ruby supplies the flattened config and applies the realignment via AlignmentCorrector (the same division of labour as FirstArrayElementIndentation). 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, colon_separator, rocket_separator]. The enforce flag replicates enforce_first_argument_with_fixed_indentation?: when Layout/ArgumentAlignment enforces with_fixed_indentation, the cop stops letting a ( claim a hash (it does NOT stand the cop down, and there is no style exemption — unlike the array cop). The separator flags replicate separator_style?, which reads Layout/HashAlignment's Enforced{Colon,HashRocket}Style.
