draxl_parser/lib.rs
1#![forbid(unsafe_code)]
2//! Hand-written lexer and parser for the current Draxl Rust profile.
3//!
4//! The crate is intentionally small and explicit:
5//!
6//! - `syntax` defines the token model shared by the lexer and parser
7//! - `lexer` turns source text into tokens
8//! - `parser` builds a typed Draxl AST from those tokens
9//! - `error` provides parse errors with stable span and line/column reporting
