7//! `PostgreSQL` wire protocol 3.0 through 3.2 primitives for UQA-compatible servers.
8//!
9//! This crate intentionally stops at protocol parsing and message encoding.
10//! It does not own sockets, tasks, TLS, authentication storage, query
11//! planning, or SQL execution. Integrators feed byte slices into the frontend
12//! decoders and translate decoded protocol messages into their own server and
13//! engine logic.
14//!
15//! Consequently this crate preserves cancellation requests, explicit error
16//! responses, and failed-transaction status bytes, but it cannot decide when
17//! an engine error or rollback must produce them. That mapping is a required
18//! responsibility of the embedding server; there is no query-execution bridge
19//! in this crate that could turn an execution failure into an empty success.
