Approaches to defining struct fields
When declaring structs, you often need to limit or control the behavior of its field members. In this section, we will see how to implement such behavior, which includes the following:
- Adding multiple mutable fields to a struct
- Grouping fields in a struct using access modifiers
- Defining required fields in a struct
- Defining struct fields with default values
Let's discuss each of these in detail in the following subsections.
Adding multiple mutable fields to a struct
We can define all the mutable fields of a struct using the mut keyword followed by : on a separate line. The syntax for defining mutable fields in a struct is shown here:
struct Note {
id int
mut:
message string
status bool
}
In the preceding code example...
