Each time a new record is inserted the object receives the same ObjectId.
Sample Code:
Unable to find source-code formatter for language: rust.

use std::error::Error;
use serde::{Deserialize, Serialize};
use mongodb::{Client, bson::oid::ObjectId};
#[derive(Debug, Deserialize, Serialize)]
struct Project {
key: String,
}
#[tokio::main(flavor = "multi_thread", worker_threads = 5)]
async fn main() -> Result<(), Box<dyn Error>> {
let client = Client::with_uri_str("mongodb://root:root@localhost:27017").await?;
let db = client.database("playground");
let coll = db.collection::<Project>("projects");
let res = coll.insert_one(Project { key: "test".to_string() }, None).await?;
println!("{:?}", res);
Ok(())
}
Every time I run the code above it prints {{InsertOneResult { inserted_id: ObjectId("60fd320b00a3d58a0077e8cb") }}}
Adding an _id: ObjectId field to the struct and then constructing the object as follows {{Project { _id: ObjectId::new(), key: "test2".to_string()} }}results in the same behavior.
The document even receives the same ObjectId when the key is different each time.
