scripts: generate_rust_analyzer.py: define scripts

2026-04-27T13:27:28+00:00

[ Upstream commit 36c619f6bd793493294becb10a02fea370b67a91 ]

Add IDE support for host-side scripts written in Rust. This support has
been missing since these scripts were initially added in commit
9a8ff24ce584 ("scripts: add `generate_rust_target.rs`"), thus add it.

Change the existing instance of extension stripping to
`pathlib.Path.stem` to maintain code consistency.

scripts: generate_rust_analyzer: Add compiler_builtins -> core dep

Add a dependency edge from `compiler_builtins` to `core` to

scripts: generate_rust_analyzer: fix resolution of #[pin_data] macros

2026-02-06T15:57:42+00:00

commit e440bc5c190cd0e5f148b2892aeb1f4bbbf54507 upstream.

Currently, rust-analyzer fails to properly resolve structs annotated with
`#[pin_data]`. This prevents IDE features like "Go to Definition" from
working correctly for those structs.

Add the missing configuration to `generate_rust_analyzer.py` to ensure
the `pin-init` crate macros are handled correctly.

scripts: generate_rust_analyzer: remove sysroot assertion

2026-02-06T15:57:42+00:00

commit 1b83ef9f7ad4635c913b80ef5e718f95f48e85af upstream.

With nixpkgs's rustc, rust-src component is not bundled
with the compiler by default and is instead provided from
a separate store path, so this assumption does not hold.

The assertion assumes these paths are in the same location
which causes `make LLVM=1 rust-analyzer` to fail on NixOS.

Commit d7659acca7a3 ("rust: add pin-init crate build infrastructure")
did not add dependencies to `pin_init_internal`, resulting in broken
navigation. Thus add them now.

[ Tamir elaborates:

  "before this series, go-to-symbol from pin_init_internal to e.g.

rust: compile libcore with edition 2024 for 1.87+

2025-05-25T20:59:47+00:00

Rust 1.87 (released on 2025-05-15) compiles core library with edition
2024 instead of 2021 [1]. Ensure that the edition matches libcore's
expectation to avoid potential breakage.

[ J3m3 reported in Zulip [2] that the `rust-analyzer` target was
  broken after this patch -- indeed, we need to avoid `core-cfgs`
  since those are passed to the `rust-analyzer` target.

  So, instead, I tweaked the patch to create a new `core-edition`
  variable and explicitly mention the `--edition` flag instead of
  reusing `core-cfg`s.

  In addition, pass a new argument using this new variable to
  `generate_rust_analyzer.py` so that we set the right edition there.

  By the way, for future reference: the `filter-out` change is needed
  for Rust < 1.87, since otherwise we would skip the `--edition=2021`
  we just added, ending up with no edition flag, and thus the compiler
  would default to the 2015 one.
