graphforge-ast 0.5.1

//! GraphForge AST — syntax-faithful, span-rich parse tree.
//!
//! The AST is internal to the compiler pipeline. `graphforge-cypher` produces it;
//! `graphforge-ir` consumes it. No other crate should depend on this crate directly.
//!
//! # Module layout
//!
//! - [`token`] — `Token` enum and `Keyword` enum (frozen lexer ABI)
//! - [`parse_error`] — `ParseError` and `ParseErrorKind`
//! - [`ast`] — all AST node types
#![forbid(unsafe_code)]
