type-bridge-core-lib

Pure-Rust TypeQL AST, schema parser, query compiler, validation engine, and value coercer for type-bridge.

This is a supporting engine crate. Most applications should consume generated models through type-bridge instead.

[dependencies]
type-bridge-core-lib = "2.2.2"

Modules

Module	Purpose
`ast`	TypeQL Abstract Syntax Tree — patterns, statements, clauses, and values
`validation`	Schema-aware query validation plus a portable JSON validation-rule DSL
`compiler`	Compiles an AST back into a TypeQL query string
`query_parser`	Parses a TypeQL query string into the AST (bidirectional round-trip)
`value_coercion`	Coerces raw values into TypeDB value-types and formats TypeQL literals
`reserved_words`	TypeQL reserved-word detection

Usage

use type_bridge_core_lib::query_parser::parse_typeql_query;
use type_bridge_core_lib::compiler::QueryCompiler;

// Parse a TypeQL query into AST clauses
let clauses = parse_typeql_query(r#"match $p isa person, has name "Alice";"#).unwrap();

// Compile back to TypeQL
let compiler = QueryCompiler::new();
let typeql = compiler.compile(&clauses);
assert_eq!(
    typeql,
    r#"match
$p isa person, has name "Alice";"#,
);

Canonical Split-YAML schema loading and resolution live in type-bridge-schema. The hidden frozen parser/schema modules in this crate are compatibility machinery, not an application schema-authoring API.

Feature flags

Feature	Default	Effect
`pyo3`	no	Enables `#[derive(FromPyObject)]` on AST types for PyO3 interop

Testing

cargo test -p type-bridge-core-lib

Compatibility

This crate is released in lockstep with TypeBridge 2.2.2 and requires Rust 1.88+. Database-facing TypeBridge 2.1 components support TypeDB 3.11.x–3.12.x, with 3.12.1 as the V2 semantic baseline.
