Overview

Drop-in Rust reimplementation of Layout/InitialIndentation.

Rust answers only the cheap question — "is the first non-comment token indented?" — with a leading-byte scan that never materializes the token stream. On the overwhelming majority of files (column-0 start) the scan settles it and this cop touches no tokens, which is the whole point: stock's first_token forces the parser-gem token stream on EVERY file (the "toucher" cost).

Only when the scan reports an offense does the wrapper fall through to stock's exact first_token / space_before construction (below, verbatim from vendor/rubocop/lib/rubocop/cop/layout/initial_indentation.rb). Because that construction is stock's own code, the offense range and the autocorrect bytes are byte-identical by construction; the Rust scan is a pure speed gate. The scan can only over-report (it never skips a token stock keeps), and space_before's column.zero? / no-space-to-the-left guards filter any over-report back to stock's answer.
