A struct literal denotes a newly allocated struct value by listing the values of its fields. You can list just a subset of fields by using the Name: syntax. (And the order of named fields is irrelevant.) The special prefix & constructs a pointer to a…

Map literals are like struct literals, but the keys are required. package main import "fmt" type Vertex struct { Lat, Long float64 } var m = map[string]Vertex { "Bell Labs": Vertex { 40.6833, -74.39967, }, "Google": Vertex{ 3…

If the top-level type is just a type name, you can omit it from the elements of the literal. package main import "fmt" type Vertex struct { Lat, Long float64 } var m = map[string]Vertex { "Bell Labs": {40.68433,-74.39967}, "Google…

Struct fields are accessed using a dot. package main import "fmt" type Vertex struct { X int Y int } func main() { v := Vertex{, } v.X = fmt.Println(v.X) }…
