Modules

ast

Internal SQL AST. Lifts the relevant subset of the libpg_query protobuf tree into a Rust enum the compiler walks. Statements not yet supported parse cleanly but compile to crate::SQLError::Unsupported.

compiler

Lift a PostgreSQL parse tree into the internal Statement AST.

error

Error types surfaced by the SQL compiler and executor.

expr

Scalar expression evaluator: turns an Expr into a Value under a row context (column -> value) and a parameter binding.

fts_query

Full-text search query-string parser.

params

Bind parameters for Engine::sql(query, params).

plpgsql

PL/pgSQL function bodies: typed AST, parser, and the variable binding rewriter.

registry

Function registry: maps SQL function names called inside WHERE / projections to UQA-side semantics (text match, vector knn, hybrid fusion, …).

result

Result rows returned by Engine::sql.

Traits

AsyncSQLEngine

Common asynchronous SQL interface implemented by embedded and HTTP engines.
