Overview

Drop-in Rust reimplementation of Layout/SpaceInsideHashLiteralBraces.

Rust walks the AST once, replicating stock's on_hash / on_hash_pattern over hash literals and braced hash patterns: the left-brace check (skipped across a line break or before a comment), the right-brace check, and the whitespace-only-inner check under the no_space empty style. The compact style's same-brace-token test on the right (tRCURLY vs a %w{...} tSTRING_END) is resolved from the collected hash / hash-pattern / brace-block / brace-lambda closing positions.

Each offense comes back as [start, end, message_code]. The corrector follows stock's autocorrect, keyed on the live range.source: a whitespace range is removed, a { gets a space after, anything else a space before. Stock can emit the same range twice for { } (the left-brace check and the whitespace-only check); add_offense dedups by location on both sides, so the duplicate is forwarded as-is.
