You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: struct-map-key.go
    path of file: ./repos/Rust-Full-Stack/golang/examples/struct
    
    the code of the file until where you have to start completion: package main

import "fmt"

type Measure struct {
    size int
    unit string
}

func main() {
    // A map with struct keys.
    storage := map[Measure]bool{}

    // Add 3 structs as keys in the map.
    m := new(Measure)
    m.size = 10
    m.unit = "centimeters"
    storage[*m] = true

    m = new(Measure)
    m.size = 20
    m.unit = "feet"
   
    
func main() {
    // A map with struct keys.
    storage := map[Measure]bool{}

    // Add 3 structs as keys in the map.
    m := new(Measure)
    m.size = 10
    m.unit = "centimeters"
    storage[*m] = true

    m = new(Measure)
    m.size = 20
    m.unit = "feet"
    storage[*m] = true

    m = new(Measure)
    m.size = 10
    m.unit = "decibels"
    storage[*m] = true

    // There are 3 keys in the map.
    fmt.Println("Map len", len(storage))

    // Create structs to look up values in the map.
    key := new(Measure)
    key.size = 10
    key.unit = "centimeters"
    v := storage[*key]
    fmt.Println("Result", key, v)

    key = new(Measure)
    key.size = 100
    key.unit = "decibels"
    v = storage[*key]
    fmt.Println("Result", key, v)
}
