From d7659acca7a390b5830f0b67f3aa4a5f9929ab79 Mon Sep 17 00:00:00 2001 From: Miguel Ojeda Date: Sat, 8 Mar 2025 11:05:01 +0000 Subject: rust: add pin-init crate build infrastructure Add infrastructure for moving the initialization API to its own crate. Covers all make targets such as `rust-analyzer` and `rustdoc`. The tests of pin-init are not added to `rusttest`, as they are already tested in the user-space repository [1].

[ Remove the `expect` (and thus the `lint_reasons` feature) since the tree now uses `quote!` from `rust/macros/export.rs`. Remove the `TokenStream` import removal, since it is now used as well. In addition, temporarily (i.e. just for this commit) use an `--extern force:alloc` to prevent an unknown `new_uninit` error in the `rustdoc` target.
