Struct, Methods, & Interfaces

• struct is a named collection of fields where you can store data
• can access fields of a struct with struct.field syntax
• g will print a more precise decimal number than f
• method is a function with a receiver (a struct)
• called by invoking them on an instance of a particular type
• interface define functions that can be used by different types
• if a struct has those methods then they implement the interface
• used to decouple as the internals of a struct can be hidden if they are referred to thorough there interface
• table driven tests are used to test a list of test cases that can be tested in the same manner
• %#v will print a struct with the fields and values
