rustc has a lot of important data structures. This is an attempt to give some guidance on where to learn more about some of the key data structures of the compiler.
| Item | Kind | Short description | Chapter | Declaration |
|---|---|---|---|---|
CodeMap |
struct | The CodeMap maps the AST nodes to their source code | The parser | src/libsyntax/codemap.rs |
ParseSess |
struct | This struct contains information about a parsing session | The parser | src/libsyntax/parse/mod.rs |
TraitDef |
struct | This struct contains a trait's definition with type information | The ty modules |
src/librustc/ty/trait_def.rs |
TyCtxt<'cx, 'tcx, 'tcx> |
type | The "typing context". This is the central data structure in the compiler. It is the context that you use to perform all manner of queries. | The ty modules |
src/librustc/ty/context.rs |
