impl From<Order> for Bson
[src]
impl From<Order> for Bson
This impl is provided so that you can use these more expressive ordering
names instead of the not very clear 1
and -1
when constructing literal
BSON index documents, like this:
let index = doc! { "_id": Order::Ascending, "zip": Order::Descending, };
