Since 1, this will come automatically from rustc-std-workspace-core and the crates.io dependency should no longer be specified.

This will need to wait for rust-lang/rust#141993, @dvdhrm after that merges would it be possible to merge this and do a patch release? So we can update the version used in Rust's std.

Sure! Thanks for the update!

Thanks a lot! I will push out a minor release with this applied.

dvdhrm · 2025-06-17T09:05:28Z

Can you elaborate on what happens if someone now builds an older version of rustc? They will likely have the previous version of r-efi pinned, so I guess this works. But from a semver-perspective, this is kind of a breaking change. I don't think this matters much, since we never promised the rustc-build-integration is part of the stable API, but still wondering how you ensure older rustc still builds?

dvdhrm · 2025-06-17T09:13:39Z

All of this is pretty true; std always builds with --locked so older builds won't pick this up by accident. It also won't be possible for old builds of rustc to update past this version, but there isn't any reason that should be a problem. And then indeed, the exact behavior of rustc-dep-of-std deps is pretty tied to nonpublic rustc and std internals, so no semver guarantees are necessary :)

Thanks for the explanation! Sounds all good.
