Go Structs.
Structs are“and” types.
When should we use structs over a class?
In C structs are very different from classes.
Struct members cannot be declared as protected because structs do not support inheritance.
However, in C structs and classes are very different.
It has to be fluid and change according to modifications being made in the respective entities(properties, methods,classes, structs, enums).
Structs are a way of creating more complex data types.
Bond generated c++ structs can also use custom allocators.
Structs are particularly useful for small data structures that have value semantics.
The privacy rules apply to structs, enums, functions, and methods as well as modules.
Structs follow the same rules as any other data type- everything must be initialized before use.
The primary difference is that structs are value types and classes are reference types.
All structs inherit directly from System. ValueType, which inherits from System. Object.
XML-RPC parameters are a simple list of types and content- structs and arrays are the most complex types available.
Because structs are implicitly sealed, they cannot be inherited.
Predefined value types such as int are treated specially in a few ways butare for the most part treated exactly like other structs.
Unlike classes, structs are value types and do not require heap allocation.
Structs are best suited for small data structures that contain primarily data that is not intended to be modified after the struct is created.
For small classes and structs, it is not necessary to separate the method declaration from the implementation.
Structs are best suited for small data structures that contain primarily data that is not intended to be modified after the struct is created.
The first difference is that structs get copied whenever they're assigned to a variable or passed to a function.
Because structs are really intended to group data items together, you will sometimes find that most or all of their fields are declared as public.
Generics permit classes, interfaces, structs, delegates and methods to be parameterized by the types of data they store and manipulate.
Classes and structs are two of the basic constructs of the common type system in the. NET Framework.
Furthermore, because structs are not reference types, it is not possible for values of a struct type to be null.
However, for simple structs, many developes would nevertheless consider public fields to be acceptable programming practice.
The members of anonymous structs are promoted to the scope of the containing struct and looked up like ordinary members.
Nested types- classes, structs, and enums- are listed alongside properties and methods, which takes a little getting used to.
Chapter 5 discusses structs and methods, and Chapter 6 covers enums, match expressions, and the if let control flow construct.
