Overview

Drop-in Rust reimplementation of Layout/EmptyLinesAroundArguments.

Rust walks the AST, reproduces the stock cop's on_send / on_csend over every multi-line call (with at least one argument whose receiver and selector share a line), scans each argument's source_range.begin and the closing )/] for a preceding run of whitespace spanning a full empty line, and returns, per offense, the offense line range. Ruby reports the range and removes it, exactly like stock's corrector.remove(range).

The cop has no configuration, so it is always bundle eligible; the offenses come from the per-file bundled run (Shirobai::Dispatch). The autocorrect re-passes re-investigate a fresh ProcessedSource, which recomputes the bundle from scratch, so this cop keeps no cross-pass state.

.bundle_args(_config) ⇒ Object

No packed configuration: the cop contributes nothing to the bundle's (nums, lists) wire format. Kept for symmetry with the other wrappers.
