Go Structs

Internal

• The Type System

Overview

A struct is a user-defined type that contains named fields.

Definition

The struct type definition is introduced by the type keyword, to indicated that this is a user-defined type, followed by the type name and the keyword struct. Each field has a name and a type.

type myStruct struct {
    i int
    s string
}

Fields with the same types can be collapsed:

type myStruct struct {
    ...
    i, j, k int
   ...
}

Are all users can define (in terms of types) structs, or there are other user-defined types?

Fields

A field is always exported by the package it is enclosed in.
