From 79b504e55cd4c4d1da102c3a076dc2a2e1edcd65 Mon Sep 17 00:00:00 2001 From: nsfisis Date: Mon, 17 Aug 2026 08:05:42 +0900 Subject: refactor(pcre): return the Preg $matches instead of filling an out-param `Composer\Pcre\Preg` fills `$matches` through a by-ref parameter, and the port mirrored that with a `&mut` (or `Option<&mut>`) out-param plus a bool or count return. Callers had to declare an empty map one line ahead of the call, and the type never said the map is only meaningful when the call matched. Return the matches instead: - match3/match4/is_match3/is_match4 -> Option - is_match_named -> Option - match_all2/is_match_all -> PregMatchesAll - is_match_all_with_offsets3 -> PregMatchesAllWithOffsets Nothing is lost: the bool is `Option::is_some()`, and the occurrence count is the length of any one column of a PREG_PATTERN_ORDER map, now spelled `PregMatchesAll::occurrence_count()`. is_match() still answers the bool question directly for callers that want no groups.
