pub fn report(event: Event)Expand description
Report one real unit of already-completed transfer work to the
current thread’s installed reporter, if any. A no-op — a single
thread-local check — when no Guard is active on this thread,
which is the default for every caller that doesn’t opt in (including
every existing test that drives push_branch_with_depth /
push_all / pull_all / fetch_all directly).
