String() Method and Format Specifiers
Explore how to create custom string representations for Go structs by implementing the String() method. Understand how fmt.Printf and related functions use this method with format specifiers to produce readable and informative outputs, and learn to avoid common errors like infinite recursion.
We'll cover the following...
When you define a type with a lot of methods, chances are you will want to make a customized string-output for it with the String( ) method, in other words: a human-readable and printable output. This is because if String( ) is defined for a certain type, then this method will be used in fmt.Printf() to produce the default output, which is the output produced with the format specifier %v. Furthermore, fmt.Print() and fmt.Println() will automatically use the String( ) method.
We will test this out with the help ...
