surrealdb-core 3.3.1

//! Plan-time utility helpers.
//!
//! Organised into focused submodules; this `mod.rs` re-exports the
//! complete public surface so `use super::util::{…}` keeps working
//! unchanged in callers (`select.rs`, `source.rs`, `aggregate.rs`).
//!
//! - [`literals`] — pure value/expression conversion and the constant folder used to reduce
//!   deterministic WHERE expressions to literals.
//! - [`conditions`] — predicate analysis (top-level OR, KNN/FTS detection), condition stripping
//!   after a scan operator has consumed a predicate, record-ID point-lookup detection, and MATCHES
//!   context collection.
//! - [`params`] — plan-time bind-parameter resolution and projection function-to-idiom rewriting.
//! - [`fields`] — field-name and field-path derivation, GROUP BY row-scope validation, and the path
//!   overlap the restricted-field guards compare by.
//! - [`optimization`] — fast-path eligibility (CountScan/IndexCountScan, ORDER BY pushdown,
//!   sort-elimination, VERSION extraction, LIMIT helpers).
