Hi guys 🤗. I'm tinkering with Rust (Nightly 1.52.0) and I was including Rocket's contrib package into the cargo.toml.

The project blew up when I tried to build it. It said to summit the issue, so here I am.

Code

Cargo.toml

[package]
name = "backend"
version = "0.1.0"
authors = ["Jose Asilis <[email protected]>"]
edition = "2018"

# See more keys and their definitions at https://doc.rust-lang.org/cargo/reference/manifest.html

[dependencies]
rocket = "0.4.7"

[dependencies.rocket_contrib]
version = "0.4.7"
default-features = false
features = ["json", "serve"]

#![feature(proc_macro_hygiene, decl_macro)]

#[macro_use] extern crate rocket;

mod routes;

use routes::hello::hello_world;


#[get("/")]
fn index() -> &'static str {
    "Hello, world!"
}

fn main() {
    
    rocket::ignite().mount("/api", routes![index, hello_world::world, hello_world::user]).launch();
}

I ended up deleting the target folder and re-building the project again and it worked without problems.

Thanks for filing the bug report! We just shipped a patch release to work around this issue and are currently triaging related issues related to ensure each underlying problem gets resolved. Since this appears to be a duplicate of #83259, I'm going to close in favor of that issue.
