How to Assign Values Between Similar Go Structs with Different Types?

Assigning Values Between Similar Structs with Distinct Types

Having structs with identical members but different types can create the need to transfer data between them. In such cases, a type conversion can provide a solution.

Consider the following struct definitions:

type Common struct {
    Gender int
    From   string
    To     string
}

type Foo struct {
    Id    string
    Name  string
    Extra Common
}

type Bar struct {
    Id    string
    Name  string
    Extra Common
}

To transfer values from a Foo struct to a Bar struct, you can use a type conversion:

foo := Foo{Id: "123", Name: "Joe"}
bar := Bar(foo)

In this case, the conversion works because the underlying types of Foo and Bar are identical except for their struct tags. The conversion automatically assigns the values of the Common member of foo to the corresponding member of bar.
