Upon review, I realized there is an error in the `fmt::Display` implementation for the `Machine` struct. The `model_id` was used twice in the `write!` macro, while the name of the machine was not included. Below is the corrected version of the Rust struct:

```rust
use std::fmt;
use chrono::NaiveDate;
use uuid::Uuid;

#[derive(Debug)]
struct Machine {
    name: String,
    serial_number: String,
    build_date: NaiveDate,
    location: String,
    model_id: Uuid,
}

impl fmt::Display for Machine {
    fn fmt(&self, f: &mut fmt::Formatter) -> fmt::Result {
        write!(
            f,
            "Machine: {}\nSerial Number: {}\nBuild Date: {}\nLocation: {}\nModel ID: {}",
            self.name, self.serial_number, self.build_date, self.location, self.model_id
        )
    }
}

fn main() {
    let machine = Machine {
        name: String::from("Excavator"),
        serial_number: String::from("ABC123"),
        build_date: NaiveDate::from_ymd(2023, 4, 20),
        location: String::from("Warehouse 4"),
        model_id: Uuid::new_v4(),
    };

    println!("{}", machine);
}
```

This code should work as expected, given that you have the `chrono` and `uuid` crates in your `Cargo.toml` file. The output of the `println!` macro will now include the name of the machine:

```
Machine: Excavator
Serial Number: ABC123
Build Date: 2023-04-20
Location: Warehouse 4
Model ID: 67b3805e-8c98-42fb-96b2-b25b19e8d22c
```
