type CvtOp

type StructOption

type StructOption struct {
	BannedFields []string
	AliasFields  map[string]string
}

StructOption describe options in converting struct. BannedFields lists fields that are not allowed to be converted in dst struct. AliasFields lists fields that are supposed to use alias field-name in dst struct when converting. Both BannedFields and AliasFields support nested fields. For example, `A.B` in BannedFields or key of AliasFields means `A` field in dst struct is a struct, and the option is applied to `B` field in `A`.
