//! Document-support, payload, scoring, and fusion operators over posting lists.

//! Operators form a monoid under composition (Theorem 3.2.3, Paper 1):
//! every concrete operator's `execute` returns a `PostingList`, and
//! [`ComposedOperator`] is associative with the empty operator as
//! identity.
