Using Structs to Structure Related Data

A struct, or structure, is a custom data type that lets us name and package together multiple related values that make up a meaningful group. If you’re familiar with an object-oriented language, a struct is like an object’s data attributes. In this chapter, we’ll compare and contrast tuples with structs, demonstrate how to use structs, and discuss how to define methods and associated functions to specify behavior associated with a struct’s data. The struct and enum (which is discussed in Chapter 6) concepts are the building blocks for creating new types in your program’s domain to take full advantage of Rust’s compile time type checking.
