Description

Because of this, the documentation built on docs.rs broke.

Same issue on aarch64-apple-darwin

[PonasKovas]

Getting the same error on my machine, my guess is it has to do with rust 1.91 nightly because I updated today and before that there were no problems

[AdamJSoftware]

getting the same error (rustc 1.91.0-nightly)

[dnjscksdn98]

Getting the same error when building with docker image (rustlang/rust:nightly-slim). Is there any potential solutions

[anlumo]

Getting the same issue in my project, this is not just about documentation.

[dnjscksdn98]

Instead of using nightly, I've changed it to use stable version. Now it works

[bionicles]

not sure it's a sqlx issue, could be a rustc issue,

rustup default nightly-2025-08-08 worked for me

[kanarus]

I got that too, broken (only) on nightly

[kanarus]

could be a rustc issue

sounds right, found an rust-lang/rust's side issue and fix PR:

• sqlx-postgres Fails to Build on Latest 1.91.0 rust-lang/rust#145288
• actually provide the correct args to coroutine witnesses rust-lang/rust#145338

[iamjpotts]

I am not currently able to reproduce the crash with cargo +nightly rustdoc --lib --all-features on nightly-x86_64-unknown-linux-gnu updated - rustc 1.91.0-nightly (6ba0ce409 2025-08-21) (from rustc 1.91.0-nightly (9eb4a2652 2025-08-18))

The linked rust pr is now merged.

The docs for sqlx-postgres@0.8.6 have been built successfully: https://docs.rs/sqlx-postgres/0.8.6/sqlx_postgres/index.html

Closing as fixed.
