mgo Bulk() example

[S.]

hello, 

could you please show me the example of new Bulk interface? 
i'm trying this one

docs := make([]interface{}, len(myarr))

for i := 0; i < len(myarr); i++ {

docs[i] = mystruct{myarr[i]}

}

......................

t.Bulk().Insert(docs...)
res, err := t.Bulk().Run()


 but it returns error - "Client Error: Remaining data too small for BSON object"

[S.]

well, I guess I gound the answer, the code should be shomething like that:

x := t.Bulk()

x.Insert(docs...)

res, err := x.Run()

but, I was hoping it will Insert documents no matter if the will be duplicated documents with unique index (just dropping it).
Instead, it have same behaviour as usual mgo.Insert(docs...) - no inserts and return the same error.
How could I make mgo to  bulk insert only unique documents and drop duplicates? 

[S.]

well, I finally figured it out, 

the final code is:

x := t.Bulk()
x.Unordered() //magic! :)
x.Insert(docs...)
res, err := x.Run()

thank you :)
