Overview

Drop-in Rust reimplementation of ‘Style/NestedParenthesizedCalls`.

Detection and autocorrect both happen in Rust; Ruby turns the byte offsets handed back into offenses and corrector ops. The corrector builds an ‘range_with_surrounding_space(side: :left)` analogue (`[ac_open_start, ac_open_end)` → `(`) plus an `insert_after` at `ac_close_pos`, matching stock byte-for-byte.

‘AllowedMethods` is taken from the cop’s own config (plus the deprecated ‘IgnoredMethods` / `ExcludedMethods` aliases for parity with stock’s ‘AllowedMethods` mixin). `Regexp` entries are not supported on the bundle path; if any regexp is configured, the wrapper falls back to the standalone per-cop call instead.

.bundle_args(config) ⇒ Object

Returns ‘[allowed_methods]`. `allowed_methods` mirrors the stock `AllowedMethods` mixin: `AllowedMethods` + deprecated `IgnoredMethods` + `ExcludedMethods`, with `Regexp` entries dropped (the bundle path accepts string names only). When any regexp is present `bundle_args` still returns the strings; the wrapper detects the regexp in `bundle_eligible?` and uses the standalone path instead.

  # Regexps out (rare in practice, and we fall back when present).
