//! Per-field filter method emitters used by relation filter codegen.
//!
//! All emitted methods are `self`-consuming builders, so they fold the
//! runtime `self.hops` path into the resulting `FilterExpr` via
//! [`cratestack_sql::wrap_filter`]. The previous free-function variants
//! (`post::author::profile::nickname_eq(..)`) were removed: addressing a
//! relation path by *module path* is precisely what forced one emitted
//! module per distinct path, i.e. the exponential blowup in
//! cratestack#252. The chained form
//! (`post::author().profile().nickname().eq(..)`) is the 1:1 replacement.
