kglite 0.10.9

Pure-Rust knowledge graph engine — Cypher pipeline, snapshot/working CoW transactions, columnar/mmap/disk storage backends, optional dataset loaders (SEC EDGAR, Sodir, Wikidata). PyO3 wrappers live in the sibling kglite-py crate (the Python wheel); embeddable directly from any Rust binary without PyO3 in the dep tree.

//! Pattern matching — parse and match Cypher-style patterns against a DirGraph.
//!
//! Split into three submodules:
//! - [`pattern`] — AST types (Pattern, NodePattern, EdgePattern, PropertyMatcher, etc.)
//! - [`parser`] — tokenizer + Parser that turns pattern strings into the AST
//! - [`matcher`] — PatternExecutor state machine that runs matches against a graph
//!
//! The PropertyMatcher enum is defined in `pattern` with its cases, its
//! construction in the Parser, and its evaluation in `matcher::PatternExecutor`.
//! The three files deliberately mirror the lifecycle of a pattern: parsed,
//! typed, then matched.
