A high performance, correctness-oriented Solidity parser + other tools.
The produced AST is mostly grammar.txt compliant. The AST is statically typed to make sure that it is not possible to construct an AST representation of what would be illegal grammar.
It's really fast.
Running target/release/deps/second_price_auction-2b369ce54b97fb9f
running 2 tests
test parse_to_ast ... bench: 24,028 ns/iter (+/- 573) = 562 MB/s
test tokenize ... bench: 15,037 ns/iter (+/- 1,405) = 898 MB/s
Neither the lexer nor the parser ever backtrack while reading bytes/tokens. The parser is using a paginated arena allocator to avoid heap allocation costs (or garbage collection costs, or anything else).
Feel free to rerun the benchmarks (requires nightly Rust, with rustup: rustup run nightly cargo bench)
