1//! The `queryweave` derives, under the default conventions.
2//!
3//! Each derive forwards to its function in `queryweave-codegen` with
4//! `DefaultConventions`; see there for what each one generates. A crate
5//! wanting other naming rules or runtime paths writes its own proc-macro crate
6//! calling those functions with its own conventions.
