Running into not all trait items implemented, missing: Body`` in latest axum

[IanQS]

• I have looked for existing issues (including closed) about this

The closest thing I could find was Support generating OpenAPI/Swagger docs where the user discussed RequestBody, but that's definitely not particularly relevant.

Bug Report

Version

My dependencies are

axum = "0.6.12"
tokio = { version = "1.27.0", features = ["full"] }
tracing = "0.1.37"
tracing-subscriber = { version = "0.3.16", features = ["env-filter"] }
sqlx = { version = "0.6.3", features = ["runtime-tokio-rustls", "any", "postgres"] }

as I've got in my Cargo.toml

Platform

MacOS M1 2021 model

Description

When trying the example code listed in sqlx-postgres (but with the crate versions listed above) I get

error[E0046]: not all trait items implemented, missing: `Body`

Sorry, I know this is a silly question given I'm using a completely different version, but I've tried googling this specific error around and couldn't find anything that was useful. I'm new-ish to Rust and I can't tell what exactly I need to implement for what structure - the code seems relatively uncomplicated so...?

Try cargo clean and then rebuild.

I can't reproduce the issue. I just had another thought: What is your Cargo / Rust version? (cargo --version / rustc --version)

[IanQS]

cargo 1.67.1 (8ecd4f20a 2023-01-10) and rustc 1.67.1 (d5a82bbd2 2023-02-07)

---

I just ran rustup update and had the versions

cargo 1.68.2 (6feb7c9cf 2023-03-26) and rustc 1.68.2 (9eb3afe9e 2023-03-27) where the issue persists

Hmmm, is there a chance that you accidentally edited things inside /Users/ianqs/.cargo/registry/src/github.com-1ecc6299db9ec823/axum-core-0.3.3? If you delete the directory, cargo should clone the repo again.

[IanQS]

I don't think I edited anything in there - I didn't even know where rust put its cargos. And ,whoah, that's so strange - it worked! I have no idea what's up with this but I'm glad it got resolved!

[IanQS]

Mind making your comment into a new answer so I can mark it as the solution?

[jplatte]

Solved in the other discussion – apparently the source checkout of axum-core 0.3.3 from crates.io was corrupted. Deleting the whole /Users/ianqs/.cargo/registry/src/github.com-1ecc6299db9ec823/axum-core-0.3.3 directory that contained the file which caused the error fixed it.
