Operating System

Debian 13

Rust Toolchain Version

rustc 1.88.0 (6b00bc388 2025-06-23) also tested with rustc 1.90.0 (1159e78c4 2025-09-14)

What happened?

I am writing a PR. The PR contribution guidelines say to run ./scripts/test.sh --contrib. It fails in my PR. But it also fails on current git head, ec44ab7e05810 . It fails with:

error[E0433]: failed to resolve: could not find `try_join` in `futures_util`
   --> /home/mcc/.cargo/registry/src/index.crates.io-1949cf8c6b5b557f/diesel-async-0.5.2/src/pg/mod.rs:429:23

    |                       ^^^^^^^^ could not find `try_join` in `futures_util`

For more information about this error, try `rustc --explain E0433`.
error: could not compile `diesel-async` (lib) due to 1 previous error

I don't quite understand what's happening here, and it's not clear to me the problem is in Rocket. If I had to guess, I'd guess cargo is for some reason picking an inappropriately old version of futures_util, and a Cargo.toml somewhere needs a more explicit version number.

Test Case

./scripts/test.sh --contrib

Log Output
