Trait HashCode 

pub trait HashCode {
    // Required method
    fn hash_code(&self) -> i32;
}

The hashCode function on all Java Objects

Required Methods

fn hash_code(&self) -> i32

Returns a Java hash code value for the object.

This follows the principles of the java.lang.Object.hashCode method.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
