big-code-analysis-ast

The parse and classification layer behind big-code-analysis: the tree-sitter wrappers (Node, Ancestors), the generated per-grammar kind enums, the LANG enum and language detection, the Checker / Getter / Alterator classifiers, the C-family preprocessor pass, comment stripping, and the AST dump. It computes no metric.

This crate is internal plumbing

It is published only so that big-code-analysis can be. That crate pins it at an exact =X.Y.Z version, the two are released together, and nothing here carries a stability promise of its own: names, signatures and module paths may change in any release, including a patch. Depend on big-code-analysis and reach what it re-exports (LANG, Node, MetricsError, SpaceKind, the AST dump types, the preprocessor types, the file readers), which its STABILITY.md covers. Depend on this crate directly only when you accept re-pinning on every release.

The split exists (#1376) so a second structural consumer — a linter, a call-graph builder, a language server — can share one classification layer without the metric machinery. Every per-language Cargo feature of big-code-analysis (rust, python, …, all-languages) is a feature of this crate under the same name, and the grammar crates are dependencies here.
