What is the p
See "Embedding in Go ": you embed an anonymous field in a struct: this is generally used with an embedded struct, not a basic type like string
. That type has no "promoted field" to expose.
A field or method
f
of an anonymous field in a structx
is called promoted ifx.f
is a legal selector that denotes that field or methodf
.Promoted fields act like ordinary fields of a struct except that they cannot be used as field names in composite literals of the struct.
(here string
has no field in itself)
See an example of type embedding in "Embeffffding when to use pointer".
Is it possible to access these fields like you can do with named fields?
A fmt.Println(obj.string)
would return Hello World
instead of {Hello World}
.
