pub fn build_entity_index<T>(
content: &T,
) -> HashMap<u32, (usize, usize), FxBuildHasher>Expand description
Build an entity index from content.
This intentionally shares EntityScanner’s HEADER skipping, quoted-string
semantics, and its #3395 refusal of instance names wider than u32 (reported
here, not handed back as a quietly short index), so scan and lookup agree.
