compiler 1.52.0 error with dependency oracle="0.5"

[corentinway]

Note

• It seems incremental build is failling because a cargo clean and a cargo build seems to solve the issue.
• works fine for the 1st build with beta version

Code

use oracle::{Connection, Error};

fn main() {
    println!("Hello, world!");

    let user = "xxxx";
    let password = "xxxxx";
    let url = "aaaaa-aaaaa.us.ccccc.dddddd:12347/ABCDEF";

    let conn = Connection::connect(user, password, url).unwrap();
    println!("Connected !");

    let sql = "select id from aaaaa_bbb.person where id = '1254984536' ";

    let rows = conn.query_as::<String>( sql, &[&10]).unwrap();

    for row_result in rows {
        let (id) = row_result.unwrap();
        println!("{}", id);
    }
}

Related? #85025, #85003, #83291:

Quoting @Aaron1011 :

This is a known issue - unfortunately, there isn't a fix for it at the moment. As a workaround, you can run cargo clean -p <your_crate_name>, which will allow you to compile it.

#85003 (comment)

[wesleywiser]

Thanks for filing the bug report! We are currently triaging issues related to #84970 to ensure each underlying problem gets resolved. Since this appears to be a duplicate of #83259 so I'm going to close in favor of that issue.
