## Support function
* [KeyBy](#KeyBy)
* [KeyBySlice](#KeyBySlice)
* [PluckUint64](#PluckUint64)
* [PluckString](#PluckString)
## Usage
### KeyBy
```
type Person struct {
Name string
Age int
}
people := []*Person{
{Name: "Alice", Age: 25},
{Name: "Bob", Age: 30},
{Name: "Charlie", Age: 35},
}
result := KeyBy(people, "Name").(map[string]*Person)
result["Alice"].Age // 25
```
### KeyBySlice
```
type Person struct {
Name string
Id int
}
people := []*Person{
{
Name: "Alice",
Id: 1,
},
{
Name: "Bill",
Id: 1,
},
{
Name: "Bill",
Id: 3,
},
}
result := KeyBySlice(people, "Id").(map[int][]*Person)
result[1] // [0xc000008120 0xc000008138]
result[1][0] // &{Alice 1}
```
### PluckUint64
```
type testStruct struct {
ID uint64
Name string
}
tests := []*testStruct{
{ID: 1, Name: "Alice"},
{ID: 2, Name: "Bob"},
{ID: 3, Name: "Charlie"},
}
result := PluckUint64(tests, "ID")
// result: []uint64{1, 2, 3}
```
