How to specify unique together index in gorm?

Question

type ABC struct {
ID uint
 Abc int `gorm:"unidqueIndex;
Bcd string
}

I want Field Abc and Bcd to be unique together

{Abc: 1, Bcd: "hello"} {Abc: 1, Bcd: "hi"} should be valid but

{Abc: 1, Bcd: "hello"} {Abc: 1, Bcd: "hello"} should be invalid

Give both fields the same index name.

type ABC struct {
 ID uint
 Abc int `gorm:"uniqueIndex:abc_bcd_uniq"`
 Bcd string `gorm:"uniqueIndex:abc_bcd_uniq"`
}
