Overview

Structs

• Useful for defining a unit with related information but different types
• Similar to C's structs
• type <name> struct { ... }

Eg.

type Person struct {
  Name string
  Age int
}

• Struct-Literal syntax for initializing
  • p := Person{"Gopher", 10}
• Partial initialization?
• Fields can be accessed using the . notation
  • p.Name or p.Age
• var p Person zero value?
• Structs can be anonymous too!
  • struct { ... }
• Empty structs have 0 memory usage
  • a := struct{}{}
  • a has 0 memory foot-print
  • Useful for signaling

Pointers to structs

• No dereferencing required
• Field access is simple for p := &Person{}
  • p.Name = "Gopher" vs.
  • (*p).Name = "Gopher"
