如何在Go中使用基础字符串值初始化类型？

Question

This works:

type T string
var t T = "hello"

http://play.golang.org/p/275jQ4ixvp

But this fails with cannot use s (type string) as type T in assignment

type T string
s := "world"
var t T = s

http://play.golang.org/p/vm3mC5ltcE

How can I make this second situation work?

Answer 1

Convert the string to the correct type [conversions]

http://play.golang.org/p/dkavI_QgPb

s := "world"
t := T(s)
fmt.Println(t)
