Objects are essentially known quantities of something that programming languages can use, interact with, perform computations and transformations on, and in general “consume.” ...

C# also lets us create what’s called value objects, a special type of object used in domain-driven design that allows us to articulate domain concepts simply, clearly, and concisely.

Rather than implementing an object-oriented programming architecture, the Rust language offers modular programming support, using traits rather than classes.
