pub fn entities(
root: &Path,
from: i64,
to: i64,
open: &[Vec<Arc<Open>>],
) -> Result<Results>Expand description
Every entity present in a window, with its name and how many blocks hold it.
What a “filter by service” control is populated from, and the one place
section 7.2’s resources.key becomes something a human can pick. Reads only the
resources and resource_attrs tables — tens of rows a block — so it is a
facet lookup rather than a scan, and it covers all three signals because a
service that only emits metrics still belongs in the list.
