//! A native Rust query client for Pylon — lets a Rust project run PyQL
//! queries against a Pylon-managed Postgres database directly, without
//! going through `pylon-py`/pyo3. Query results decode either into a
//! generic, dynamically-typed [`Value`]/[`Object`] or into a caller's own
//! row struct via [`Queryable`] and `#[derive(Queryable)]` — there is no
//! generated per-schema-type code either way.
//!
//! Compilation reuses `pylon_core::query::compile` as-is; connection
//! execution reuses `pylon_pgcon::PgPool`/`PgTransaction` as-is. The one
//! genuinely new piece is `decode`, which walks a compiled query's
//! `ShapeNode` alongside its decoded `DecodedValue` row — the Rust
//! counterpart of `pylon/query.py`'s `_decode` (which only ever ran
//! Python-side, operating on already-Pythonized values).
