//! terms of topological ordering, because it is only possible to paginate "backwards"
//! through events, starting at `from`.
//!
//! For example, passing a `from` token from page 2 of the results, and a `to` token
//! from page 1, would return the empty set. The caller can use a `from` token from
//! page 1 and a `to` token from page 2 to paginate over the same range, however.
