Functions

func Merge

func Merge(xs ...any) any

Merge make new struct value with the exported fields of the given structs. If some have a same name of field, the field of the last struct in the parameters is used. If non struct value is in the parameters, it would be ignored.

type A { N int `json:"n"`}
type B { S string `json:"s"`}

/*
struct{
     N int	`json:"n"`
     S string	`json:"s"`
}{
	N: 100,
	S: "sample",
}
*/
Merge(A{N:100}, B{S:"sample"})

func Of

func Of(fields ...*Field) any

Of make new struct value with the given names, values and tags as fields.

/*
struct{
     N int
     S string
}{
	N: 100,
	S: "sample",
}
*/
Of(F("N", 100), F("S", "sample"))

/*
struct{
     N int	`json:"n"`
     S string	`json:"s"`
}{
	N: 100,
	S: "sample",
}
*/
Of(F("N", 100, Tag(`json:"n"`)), F("S", "sample", Tag(`json:"s"`)))

The tags can be ommited.
