func ToMap ¶

func ToMap[T, V any, K comparable](s []T, f func(T) (K, V)) map[K]V

ToMap collects elements of slice to map, both map keys and values are produced by mapping function f.

🚀 EXAMPLE:

type Foo struct {
	ID   int
	Name string
}
mapper := func(f Foo) (int, string) { return f.ID, f.Name }
ToMap([]Foo{}, mapper) ⏩ map[int]string{}
s := []Foo{{1, "one"}, {2, "two"}, {3, "three"}}
ToMap(s, mapper)       ⏩ map[int]string{1: "one", 2: "two", 3: "three"}
