Annotations

In Java, annotations are a specialized kind of interface that allows you to add custom metadata about your code.

Here's an example of a method that's annotated with @Test to indicate that it's a test method:

@Test
public void someTestMethod() {
    // arrange
    // act
    // assert
}

The equivalent of annotations in Rust are called attributes. Here's a test method that is annotated with the #[test] attribute:

#[test]
fn some_test_method() {
    // arrange
    // act
    // assert
}
