Without this, the `vis` does not wind up in the tree anywhere, and then we get ICEs because the node-ids it refers to are not present. The motivation seemed to be documentation, but `ListStem` HIR nodes are ignored in rustdoc, from what I can tell.
This directory contains the source code of the rust project, including:
rustc
and its testslibstd
- Various submodules for tools, like rustdoc, rls, etc.
For more information on how various parts of the compiler work, see the rustc guide.
There is also useful content in the following READMEs, which are gradually being moved over to the guide:
