surrealdb-sql 3.3.2

//! The abstract syntax tree for SurrealQL.
//!
//! This is the shape a query has immediately after parsing, before any
//! lowering, name resolution, or planning. [`Ast`] is the whole of a parsed
//! query; [`Expr`] is a single expression within one.
//!
//! # Layer
//!
//! The AST is the bottom of the language stack. `surrealdb-syn` builds it and
//! `surrealdb-core` lowers it into the expression layer, so everything this
//! crate names sits below it: `surrealdb-strand`, `surrealdb-common`,
//! `surrealdb-types`, `surrealdb-iam`, and the upstream scalar crates
//! (`chrono`, `uuid`, `rust_decimal`, `regex`, `bytes`, `geo-types`). Nothing
//! here reaches up into the parser, the expression layer, the catalog, or the
//! engine.
//!
//! Lowering therefore lives with the consumer: core owns the `sql -> expr`
//! conversions in its `expr::convert` module. The conversions this crate does
//! own are the ones the orphan rule pins here, between an AST node and its
//! `surrealdb-types` counterpart.
//!
//! # Scope
//!
//! The AST is parse-only. No node is persisted, so nothing here carries a
//! storage-format guarantee and this crate does not depend on `revision`.
//! Where a vocabulary type also has to be stored, the persisted form is a
//! separate revisioned twin at the catalog layer and the two are bridged by
//! `From` in both directions, so a change to how something parses or renders
//! cannot move the bytes on disk.
//!
//! # Stability
//!
//! This crate is an internal implementation detail of SurrealDB with no
//! stability guarantee. It is scheduled for deletion once the greenfield
//! parser reaches parity and takes over the same layer, so its API surface
//! should not grow. Depend on `surrealdb` or `surrealdb-core` instead.
//!
//! <section class="warning">
//! <h3>Unstable!</h3>
//! This crate is <b>SurrealDB internal API</b>. It does not adhere to SemVer and its API is
//! free to change and break code even between patch versions. If you are looking for a stable
//! interface to the SurrealDB library please have a look at
//! <a href="https://crates.io/crates/surrealdb">the Rust SDK</a>.
