Why is the MIME type of the application Rust / x-sharedlib?

I have two Hello World programs written in C ++ and Rust:

main.cpp

#include <iostream>

using namespace std;

int main() {
    cout << "Hello World!" << endl;
}

      

        
        
        
      

    

main.rs

fn main() {
    println!("Hello World!");
}

      

        
        
        
      

    

I have compiled both of them with the following commands:

g++ main.cpp -o Test.bin

      

        
        
        
      

    

and

rustc main.rs -o Test-Rust.bin

      

        
        
        
      

    

Checking for the MIME type of the C ++ binary returned the executable as I expected:

$ file --mime-type Test.bin 
Test.bin: application/x-executable

      

        
        
        
      

    

But the Rust binary looks like a shared library:

$ file --mime-type Test-Rust.bin 
Test-Rust.bin: application/x-sharedlib

      

        
        
        
      

    

Why doesn't the Rust compiler output a simple application, for example g++

?
