Initialize nested struct definition

Solution 1
Your Contact
is a field with anonymous struct type. As such, you have to repeat the type definition:
s := &Sender{
BankCode: "BC",
Name: "NAME",
Contact: struct {
Name string
Phone string
}{
Name: "NAME",
Phone: "PHONE",
},
}
But in most cases it's better to define a separate type as rob74 proposed.
Solution 2
How about defining the two structs separately and then embedding "Contact" in "Sender"?
type Sender struct {
BankCode string
Name string
Contact
}
type Contact struct {
Name string
Phone string
}
if you do it this way, your second initialization attempt would work. Additionally, you could use "Contact" on its own.
If you really want to use the nested struct, you can use Ainar-G's answer, but this version isn't pretty (and it gets even uglier if the structs are deeply nested, as shown here), so I wouldn't do that if it can be avoided.
Solution 3
type NameType struct {
First string
Last string
}
type UserType struct {
NameType
Username string
}
user := UserType{NameType{"Eduardo", "Nunes"}, "esnunes"}
// or
user := UserType{
NameType: NameType{
First: "Eduardo",
Last: "Nunes",
},
Username: "esnunes",
}

How do you initialize the following struct?
type Sender struct { BankCode string Name string Contact struct { Name string Phone string } }
I tried:
s := &Sender{ BankCode: "BC", Name: "NAME", Contact { Name: "NAME", Phone: "PHONE", }, }
Didn't work:
mixture of field:value and value initializers undefined: Contact
I tried:
s := &Sender{ BankCode: "BC", Name: "NAME", Contact: Contact { Name: "NAME", Phone: "PHONE", }, }
Didn't work:
undefined: Contact
