Module rustc_middle::dep_graph

  • dep_node 🔒
    Nodes in the dependency graph.
  • Contains variant => str representations for constructing DepNode groups for tests.


  • This serves as an index into arrays built by make_dep_kind_array.
  • A dep-node filter goes from a user-defined string to a query over nodes. Right now the format is like this:
  • A filter like F -> G where F and G are valid dep-node filters. This can be used to test the source/target independently.
  • Data for use when recompiling the current crate.
  • A “work product” is an intermediate result that we save into the incremental directory for later re-use. The primary example are the object files that we save for each partition at code generation time.
  • A “work product” corresponds to a .o (or other) file that we save in between runs. These IDs do not have a DefId but rather some independent path or string that persists between runs without the need to be mapped or unmapped. (This ensures we can serialize them even in the absence of a tcx.)
