示例1: simpleArgApply
// simpleArgApply is used when no formatting template string is given.
func simpleArgApply(field *pb.Field, arg *pb.Argument) error {
switch val := arg.GetValue().(type) {
case *pb.Argument_Number:
field.Value = &pb.Field_Number{Number: val.Number}
case *pb.Argument_Str:
field.Value = &pb.Field_Str{Str: val.Str}
case *pb.Argument_Boolean:
field.Value = &pb.Field_Boolean{Boolean: val.Boolean}
default:
field.Value = nil
}
return nil
}示例2: ApplyArguments
// ApplyArguments takes the given arguments and uses them to satisfy a field parameter. If a single argument and no
// formatting pattern are given the single argument is used as the field value. Otherwise the arguments will be used as
// arguments to Printf with the formatting string as the pattern.
