Can I tell docs.rs to build my crate using stable Rust?

Recent changes introduced bugs into the nightly version of rustc, which prevented my crate from being built on docs.rs.
Although the bugs were patched within a few days, I still had to manually trigger a rebuild on docs.rs, which was somewhat frustrating.

I wonder if there is a way to configure docs.rs to build my crate using the stable version of Rust instead of nightly?

No, all builds use the nightly toolchain. From the docs:

All crates are built in a sandbox using the nightly release of the Rust compiler. The current version in use is rustc 1.94.0-nightly (86a49fd71 2026-01-14).
