Edit rustc_middle::dep_graph module documentation #80325

pierwill · 2020-12-23T05:25:46Z

The first commit here moves the content to mod.rs, the second contains edits.

The section I've called "DepNode creation and 'inference'" appears to have some outdated material. (DepConstructor is a struct, not an enum.)

You may also want to edit the docs for rustc_query_system::dep_graph::dep_node, which are a copy-paste of those for rustc_middle::dep_graph::dep_node.

The define_dep_nodes macro is defined in dep_node.rs.
It defines the DepKind enum, and DepConstructor.
DepNode is defined in rustc_query_system::dep_graph::dep_node.

Drive-by: DepConstructor should really just be a mod, since all it does is provide a namespace for functions constructing DepNodes.

I am not sure the API is that restricted any more. There is an escape hatch DepNode::new_no_params which is used in non-incremental runs.

Maybe that module should link to rustc_middle instead? Or use doc = include_str! to make sure they're kept in sync?

This fixes the module-level docs not rendering. (As of this writing, the module description is missing from https://doc.rust-lang.org/nightly/nightly-rustc/rustc_middle/dep_graph/index.html).
