fn child_tables(
signal: Signal,
) -> &'static [(&'static str, &'static str, &'static str)]Expand description
The child tables of each signal: emitted name, row table, attribute table.
Links are the out-edge of the correlation graph — a link’s trace_id
points at another trace, usually one this node never saw — so returning them
is the whole point of storing them. Events are a span’s log lines and are
what a waterfall shows when a row is expanded.
