英文:
Shorter way of writing singleton-structs
问题
如果我想创建一个“单例”结构体，我可以这样做：
foo := struct{
bar func(string, int, bool) error
}{ bar: func(a string, b int, c bool) error {
// ...
}}
如你所见，我必须两次写bar的签名。有没有更简洁的写法？
英文:
If I want to create a "singleton" struct, I can do the following:
foo := struct{
bar func(string, int, bool) error
}{ bar: func(a string, b int, c bool) error {
// ...
}}
as you can see I have to write bar's signature twice. Is there a shorter way to write this?

如果结构体确实只有一个字段，你可能想要改变foo的类型：
foo := func(a string, b int, c bool) error {
// ...
}
英文:
There isn't a shorter way.
If the struct really has only one field, you may want to change <code>foo</code>'s type:
foo := func(a string, b int, c bool) error {
// ...
}
