Overview

Drop-in Rust reimplementation of Layout/SpaceInsideParens.

Stock iterates sorted_tokens pairwise; Rust reconstructs the pair facts around every unmasked ( / ) byte (strings, comments, char literals and __END__ data are the only non-token paren bytes) plus one AST-collected token fact: the tLPAREN_ARG positions (the space-separated first-argument paren of a parenless call, which is not left_parens? and never fires the left-side checks).

Each offense is [start, end, code]: code 0 removes the range ("Space inside parentheses detected."), code 1 inserts a space before it ("No space inside parentheses detected.").
